I was thinking of Sri Lanka but after looking at the below map I'll except Maldives. Congrats shearzone. "The Earth's gravity field is shaped by the materials deep within the planet. This exaggerated map shows the unequal distribution of gravity due to the amount or density of materials beneath the Earth's crust. The purple regions represent areas of particularly low gravity while the orange regions represent regions with the highest gravity."

WINNERS – CONTEST FOR PHOTOS OF USC&GS, NOS, AND NGS SURVEY DISKS A large Thank You to all who submitted photographs and/or information on old survey disks. I have carefully gone through all the submittals and considered all the photographs that met the criteria of being USC&GS and NOAA agency disks and within the correct time period. Many of the photographs were excellent, but fell within the range of know dates, so did not qualify. The winners are listed below. Top prize is a commemorative brass survey mark, honoring the 200th Anniversary of the U.S. Coast & Geodetic Survey (1807 – 2007), see: http://www.flickr.com/photos/12262796@N06/3775260687/ . All other prizes are lapel pins honoring the same event, see:. http://www.flickr.com/photos/12262796@N06/3311544961/ . TOP PRIZE – Geoides for a photo of a flat, stamped plate, PID = HT0688. This is, perhaps, the “missing link” between earlier marks with letters and numbers chiseled in rock, and later survey disks with stamped letters and numbers. Difficult Run – for a photo of a hexagonally shaped, Gravity Station Reference Mark, year c1961, PID = AH7245. These are extremely rare, our gravity field surveyor says that he has only ever seen 4 of these. VagabondWV – for the photo of an old “cup” shaped disk, possibly set as a magnetic station in WV as late as 1944, PID = HX3058. Mega Scooter – for the earliest photo seen of a Magnetic Station, 1917, PID = QE0491, Astro D-Team – for the photo of a Triangulation Station disk with a very large triangle, 1921, PID = PN0027. Harry Dolphin (two) – for the photo of a Triangulation Station flat disk set in 1909, PID = QF0712. And for the photo of a 3” diameter (small) USC&GS AND STATE disk set in 1956, PID = KV0491 . Dixie Dawn – for the photo of a round, Gravity Station disk set in 1937, no PID. Shorbird – for the photo of the first disk I have seen stamped USC&GS and a city – in this case Akron, Ohio, year 1963, PID = MB1249. Thanks again. All winners please email me your snail-mail addresses so I can mail the prizes. GeorgeL NGS

Mount Everest would be my guess since it's the furthest point from the center of the Earth and hence might have less gravity pulling you down. I'm with Res on this one... The force of gravity you feel at any point on the earth should be related to the distance (radius) you are from the centre of the earth (mass) and the amount of mass enclosed within that radius. Theoretically, if you could get to the exact center of the earth, you would experience zero gravity as the radius would now equal zero, but we're talking "on" earth... not "in" earth. So we increase the radius by 8km or so (~height of everest) above sea level, without adding an equal amount of mass (not much earth up here!) so the effect of gravity will be reduced... but probably not enough to be noticed due to the lack of oxygen! Atleast that's what I seem to remember from all those Physics classes when I wasn't blowing things up! TOMTEC

Equitable? Not really, no. It sounds like souvenirs concentrated on geocaching's center of gravity at first (Dave Ulmer started in northern Oregon, Groundspeak is headquartered in Seattle) and then failed to spread out to the hinterlands before souvenirs started to sputter. The USA, Canada, and Germany are the only three nations who get souvenirs for each state/territory/province/Bundesland. They have the most cachers and the most caches -- so go figure. The four national souvenirs that were awarded next were done by vote in an attempt to be a little more equitable, and the four that got the most votes at first were the Czech Republic, Poland, Portugal, and Slovakia. Again, based on the center of gravity, just with a little more democracy thrown in. (Though I would not have expected Poland to get in based on my caching experience there a few years ago, I'm guessing it's doing better now.) And then they quit doing locality based souvenirs, though I've seen the gallery of souvenir art that's just waiting to be coded into the system. The only reason that souvenirs started to sputter is because GS cut off the fuel supply. I didn't see any indication at the time that geocachers were losing interest in region based souvenirs at the time that GS decided to stop creating new ones. While, the U.S., Canada, and a few countries in Europe may have a high percentage of geocachers, this *is* an international game that costs the same for anyone to play no matter where they live in the world. Those three areas are the only places in the world where one can obtain a region (and effectively, almost all other) souvenir. That includes five entire continents. When souvenirs were first launched they were compared to those iron on patch one can purchase at a souvenir shop which visiting some notable location. To me, it's sort of like coin or stamp collecting where the rarest, hardest to obtain have a greater value. Give me a souvenir for finding one of the 113 thousand caches in California and I go "meh". There have probably been millions of finds on those caches. It's like a coin collector getting a 2012 U.S. quarter. However, getting awarded a souvenir for finding a cache in Tanzania (with it's 69 hides, and probably only a few hundred geocachers logging them) and that would be something special.

When I worked for the DOT (retired early in 02) is was a continuing battle to preserve any survey mark. Seems to have been a sore point with many construction engineers as many could have cared less. My boss had a very contentious relationship with both the project engineers, the staking crews and inspectors who often just ignored the survey marks be them bench marks or section corners. They figure that we knew where they were so we could put them back at any time at our expense. Same with contractors, they could have cared less and some even made a point of destroying any mark they found. I recall the last incident with a contractor. There was a newer (1996) NGS BM on the project. It was protected with 2 orange NGS posts, stakes, flagging. One day I was driving by and seen the ground all torn up around the mark (it was outside of the slope stake line) and so we stopped and was looking it over when the dozer operator working down the road about 500 ft moved up to where we were and got off his dozer. He asked was that an important point? I said, it sure was and he reply was "good" and he made a few other nasty remarks saying he hated us state workers and would drive over any mark he saw. This is the attitude of many of them and there is nothing you can do about it.

Happy New Year everyone! I have reduced the prices by lowering my markup to just a couple dollars over the base cost that Shapeways charges to produce these (Shapeways determines the base price using the size and volume of each piece as well as the material used). The domed C&GS disks with stems are now $33. The hex shaped gravity disks are $35 because they are slightly larger. I just added a flat topped reference mark which is $40 because it has a much higher material volume due to the thickness of the flat topped disk and a much larger stem style. Keychain and stemless styles are now $28. The USGS marks are $30-$35 depending on the style of mark. Since the keychains are slightly cheaper than the full stem marks I'd recommend them to anyone interested in getting one of these who is concerned with the cost. They look nice on my keychain and hold up really well to the wear of rattling around in your pocket with keys and loose change since they are solid bronze , not the lower quality metals other replicas are made from. They really have a nice heft to them. The keychains are also a lot easier to enjoy and show off to friends since they are with you all the time and not gathering dust on a shelf or drawer with other trinkets . I only have a few disk styles as keychains so far (triangulation station and reference marks), but I can easily turn any of the disk styles with stems into a keychain. Just let me know what you might want to see. Also, Shapeways occasionally runs promotions for free shipping or a percentage off orders of a certain material. I can post those promotions when they come up if anyone wants. Here are some photos of the new flat topped reference mark:

Last year I acquired a Trimble 4000sst receiver and accessories. It has gotten me some interesting measurements, but doesn't qualify for the NGS program for GPS on Benchmarks because it doesn't process enough parts of the GPS signal. Recently, I bought a slightly newer model, the 4000sse, which uses all the old accessories and does qualify for OPUS shared solutions which can be used for the GPS on BM program. These receivers can be bought on eBay occasionally for a few hundred dollars, but you need to know what all is needed in the kit and to distinguish the reasonable models from the totally obsolete. Here's the setup on a tri-station with old receiver. The newer one doesn't look much different. For those who don't know about OPUS, here's a summary: The receiver records measurements every 30 seconds, and stores them essentially as a time delay from each satellite in view. You download those into a computer file and after some waiting time for CORS and orbit data to be collected, you send it to a web site at NGS. They automatically process this against CORS station data. A few minutes later it emails you a report that tells you where you were and some measures of performance. The orbit data is either "Ultra Rapid" meaning relying on predictions and available within a few hours, "Rapid" meaning updated with real measurements the next day, or "Precise" which has been processed to the best possible estimate but 2 to 3 weeks after the fact. There are two processing options, OPUS-S or static for 2 hours to 48 hours, and OPUS-RS or rapid static for 15 minutes to 2 hours. The RS algorithm is better in some ways and lets you get away with the shorter sessions for some uses, but OPUS-S with at least 4 hours is needed for any NGS use of the data. I'm hoping that when the weather warms up I can do some OPUS shared solutions on benchmarks that NGS can use as they check their gravity model. I want to have checked my results on a couple HARN stations first. Today I got the results using final "precise" orbits for a 7-hour session on a point in my back yard, processed by OPUS-S and also split into 7 sessions of 1 hour each for OPUS-RS. Here are some plots I put together to compare results. There are effects that the processing doesn't know about, so the supposed 95% confidence limits only apply to some of the error sources and can't be taken at face value. But note that the horizontal grid is 1-cm squares and the vertical grid is 2 cm. All of the horizontal position outlines would fit comfortably on a US 5-cent piece.

Ah, just like the laws of phsyics - try defying gravity and you come to the realization that while not obvious, they are still in place. The laws may be difficult to detect, but they are there and applicable. Try placing your first cache with a theme of dedication to Anarchism. You will quickly discover the "authority."

There are no GPS Observations so far. It would appear the original monumentation was 1939 and the AZ MK 1950, but the Narrative does not show the 39 monumentation and is out of usual order as well. GS0206'THERE WERE NO REFERENCE MARKS ESTABLISHED AT THIS STATION. But it has an AZ Mark... Second Order Tri stations will almost always have RM's but it is rarer for them to have and AZ Mark... But look at this one... Interesting. There has been a lot of talk here lately to have changed made to Geocaching's Data mining procedure. But the NGS Datasheet really has it all, and laid out so simple. Can I convince anyone to learn to read them? You own mind can screen it for so much info, and there is so much more I didn't address, Like a 2 some odd foot Datum Shift the 29 and 88 Vertical Datum and ho good of a Job JB's GPS Pressure aneroid did in being approximately 8 feet off the observation. Not bad. Oh and hey, I think I found where the Cairn with the lowest extreme elevation in the country is located, and it has no recoveries: GS0908 GS0908 HISTORY - Date Condition Report By GS0908 HISTORY - 1950 MONUMENTED CGS GS0908 GS0908 STATION DESCRIPTION GS0908 GS0908'DESCRIBED BY COAST AND GEODETIC SURVEY 1950 GS0908'SEE STATION DAYTON HARRIS GRAVITY STATION TEXT So who wants a FTF on the lowest Cairn in the country? It appears to be just sitting there for the taking. Probably qualifies for one of Holographs Extreme benchmarks too! Thanks for sharing this one JB, It was very nice. Rob

" The geoid is defined as the surface of the earth's gravity field, which is approximately the same as mean sea level. It is perpendicular to the direction of gravity pull. Since the mass of the Earth is not uniform at all points, and the direction of gravity changes, the shape of the geoid is irregular." Qutoed from the Institute For Geographic Information Science here. Sorry, gravity not magnetism. It was yet another slip.

Let me tell you something about in my country the Netherlands. It is very flat here and part is below mean sealevel. And yes, it is very muddy here most of the time in most places but we do not walk in wooden shoes to keep dry feet. We have rubber boots nowadays So height has some importance to us: where want the surplus water goto? A question of millimeters. Thanks to gravity measurement we now have RDNAPTRANS™ 2004 with a new geoide. In the past the measurement equipment was transported by train late in the evening and the stuff was setup on a railwaystation platform. This was the gravity station. When trains stopped travelling and industry came to relative rest then measurements were taken of something falling in vacuum with precise (atomic?) clocks for timing. Modern technical developments make it possible to transport the gravity station by road. (for British readers: there is also mention of a Gravity Station in Doctor Who) The result of all their work is this picture where you can see that water in the North-east of the country on a distance of 40.25 m above the WGS84 ellipsoid is in equilibrium with water in the south of the country on a distance of 46.25 above the WGS84 height. This over a distance of 200 km. NLGEO2004 (in meters) ten opzichte van GRS80 (ETRS89/WGS84)

Fighting shifts in definitions is like fighting gravity. It is what it is, and it won't be stopped. (Sorry, purists, don't shoot the messenger.) Add an extra category at the upper end (Extra-Large) and Nano at the lower end.

I guess they're like this (showing the gel in the bottom). Is there also a laboratory label? That looks like a somewhat more durable tube than the flip-cap centrifuge vials. Besides cleaning out the agar (good idea), see what you can do to make these things look not like a blood sample/syringe/virus laboratory medical device. I'm already a little leery of touching the prescription bottles of whatever those pills were, of which some cacher owners have thousands of empties. You might find that the gel wipes right out with soap & water and a swab. But as mentioned, you must clean it well. That stuff is for growing microorganisms. Cache Owners are supposed to grow fungus & bacteria mainly on the log sheets and the soaking wet mass at the bottom of the container. No, it is for forming an inert barrier between the plasma and the cellular components when the tube is centrifuged. It has a specific gravity between the two. It is not agar. The FDA lists it as an inert polymer but I cannot find specifics on the composition (likely proprietary) Cool, didn't know that! To make a Nano cache, simply fill it with that polymer and water can't get in.

I doubt that the Cleveland Way will have such insurance. It's the same if you write a guide book: AFAIK there's no need to have insurance. Someone could try and sue the Cleveland Way if they slipped and fell on the section of path you're talking about but they would simply refer them to the landowner if there was evidence of negligence (for instance, if he'd dug a hole in the path and then covered it with thin plywood and someone fell through). The same if you'd written a guidebook to the Cleveland Way. I don't think it takes a lawyer to know that our victim of the hole would have little chance of suing the guidebook writer for directing them down this section of path. In your case, I think the landowner is trying to get you to take responsibility for anyone who comes a cropper on the footpath and who says that they were on their way to/from a geocache. A good thing to keep out of! That'd be like the guidebook writer accepting responsibility for accidents that happen anywhere mentioned in the book, and thus having to take out an insurance policy. Rock climbing guidebooks are potentially in a worse situation. After all, they're encouraging people with or without any knowledge of climbing safety techniques to perfom death-defying feats on various peoples' land. Usually without the landowners' knowledge or permission. And yet there's not a problem, even though I don't think that writers are insured against claims.

Anti-gravity was what H.G. Wells 'used' in "First Men in the Moon", which pre-dates Asimov. However, although anti-gravity has been used by so many sci-fi authors, it's not the answer here.

Hi all. After many years with my Magellan Triton 400, I had finally sorted out all of the bugs and my own user errors and we were getting along great.... then I left it on the roof of our van and let's just say gravity is not a friend of the Triton. It seems like the whole world uses a Garmin and neither GPScity and GPScentral even carry Magellan units so I figure it might be time to join team Garmin. I will be using the GPS mostly for geocaching with some hiking etc thrown in. I had a TOPO map for my Triton and loved it so I want to get it again with whatever unit I buy. I have a few questions about the 700 series and being new I hope someone here will have the answers. 1) Being a touch screen, is there a way to lock the screen so that if it bumps or touches something in my bag or pocket it won't change pages or start doing something it isn't supposed to? 2) I understand that you can load geocaches via WIFI when you have a computer etc. How many caches can you upload at once? When I reconnect at a later time will it delete any caches that have been discontinued so I don't accidentally search for caches that aren't there anymore? Will it automatically update all of the caches I have loaded onto it or do I have to go back to different areas on the map to update the logs etc of the caches? Will it indicate caches I have already logged with a different icon so I don't accidentally search for a previously found cache? 3) Can caches be deleted from the unit after they have been found? I looked at possibly getting an E-trex 30x but by the time I buy one and then buy the TOPO map of Canada for it, the difference in price between the E-trex30x and the Oregon 750T is only about $200. While $200 is $200 I don't want to buy something that will be badly outdated in a couple of years and I want something that I can easily load caches onto so I don't have to constantly be guessing where I'll be caching next. I hate relying on my smartphone for impromptu caching as the battery just doesn't hold up for more than one or two caches. Thanks

Yes, you can lock/unlock the screen easily. Multipart question. Multipart answer. You can always load a PQ GPX/GGZ file via computer but your questions are about Live Geocaching data. There are two ways to download Live data, 1) download a "Geocaching List" which is simply a PQ that you've built in your GC.com account, and 2) using the map, you can pan anywhere and download 25 caches that are closest to the center of the map (where you panned or you can use your current location). There is no limit (that I'm aware of) on how many times you can download the 25 caches so you can pan around to specific areas and keep downloading. The Live downloads consist of the Geocache locations without the Log/Description info. It allows you to download the Log/Description info by selecting a geocache you want to find and hit "GO". At that point the device will wirelessly download the Log/Description info. Once found, the unit will change the icon from a closed treasure box to an open treasure box. As the data will be live, the Oregon 7xx won't download caches that have been discontinued. Normally, after caches are found, they're identified as an open treasure chest icon. That icon makes identifying found caches easy. You could also filter out found caches in the geocache filter, but there seems to be reports that this ability isn't working at the moment. Garmin is aware of the issue and will likely soon issue a fix. There is no way that I'm aware of to target and outright delete found caches short of using GSAK to edit a PQ. Live Geocaching data (data downloaded wirelessly on the fly, can be deleted but it's an all or nothing kind of deal. But, with the changing of the icon, you don't really need to in my opinion. Good luck with your decision. Plenty of people like using the eTrex 30 but I feel the Oregon 7xx is in another league in many respects. Compared to the Triton 400, it's in another universe. Consider your Tritons experience with gravity a fortunate event. As someone who had a brief and disappointing run with a Triton, you're going to like using a Garmin so much more. Yoga

I believe both cache seekers and cache hiders should be personally accountable for their actions. I also believe cache hiders should warn people of significant non-obvious dangers that the hiders know about. I noticed a cache of yours had these warnings: How very "liberal" of you to include these warnings. But in your analogy, the guy walking down the street would have to sue the person who built the street so close to the building, knowing full well the effects of gravity, and the chances that people would walk down the street, near the building, thereby subjecting themselves to being hit by anything on or near that building that might suddenly find itself subject to gravity. I asked, "Why shouldn't the injured geocacher sue the cache owner for gross negligence?" Cx1 replied, "Because the cache owner did absolutely nothing to force anyone to try and find their cache." So I explained how people tossing cinder blocks off apartment balconies can act with gross negligence even if they don't force people to walk on the street below. If you want something more analogous to geocaching, then imagine a contractor builds a private road, but the surface of the road is too close to a heating tunnel that runs below it. If the engineer knew the road was likely to collapse under the weight of a typical vehicle and cause serious damage to the vehicle and/or its occupants, then that contractor probably is grossly negligent...even though the contractor never forced anybody to drive on the road. Every cache I've visited has "the possibility for injury." I've never claimed otherwise. But that doesn't suit your argument, so you created a straw man to attack instead. Beating up a straw man only makes you look foolish.

For some reason, watching the dialog between you and CanadianRocky reminded me of a line from the movie Last of the Mohicans, where the lead character Hawkeye, an adopted member of the Mohawk Indian tribe, while talking to a British Colonial woman, said, "My father warned me about you. He said 'Do not try to understand them, and do not try to make them understand you. That is because they are a breed apart and make no sense'. I think, for you and I, we should switch "British Colonials" for "Liberals". They truly believe the silliest things. And believe them with conviction. Trying to discuss notions like personal accountability with them is going to get you naught but blank looks. I'm sorry. How, exactly, does a film can "lure" anybody, anywhere? I've seen a lot of film cans over the years. I even have a grocery bag full of them on in my desk. I've never seen any of them do any physical act, up to and including "luring" people. The same is true of soda bottle preforms, bison tubes, decon kits, Lock & Locks and ammo cans. They are all inanimate objects. As far as I can tell, the motivation to hunt a cache has to come from within each seeker, when they make a conscious decision to either hunt a particular cache, or not hunt a particular cache. But in your analogy, the guy walking down the street would have to sue the person who built the street so close to the building, knowing full well the effects of gravity, and the chances that people would walk down the street, near the building, thereby subjecting themselves to being hit by anything on or near that building that might suddenly find itself subject to gravity. A reasonable person would argue that the street builder did not "lure" people to walk there. A reasonable person would also argue that walking down streets can be hazardous, and everyone who attempts such acts should take reasonable precautions when doing so, therefor, the street builder should not be held liable for any injuries incurred by people walking down their street. A reasonable person would say the same about a geocache hider. A cache hider is not analogous with a brick tosser. Actually, what he, in effect said was, "There is a cache here". If you, (the collective you, not the individual you), translate that into something like, "Come and get it", then I would argue that your reading comprehension is sufficiently poor that you, (again, the collective you), should probably never set foot outside of your house. Of course, since most accidents occur inside the home, you would probably feel I was liable for any injury you receive at home, since I suggested you stay inside. I own roughly 60 active hides, not counting sock puppets. None of them so much as hint "Come and get it". I have found roughly 1600 caches. None of them said "Come and get it" either. By your definition of liability, wouldn't any cache, hidden in a place that could lead to injury, (which, incidentally, is any place on the planet), be tempting fate? Your cache M&M is a perfect example of this. You are "luring" people to walk down into a canyon, knowing that any hike involving changing elevation carries certain risks. But you aren't even willing to add a "Dangerous Location" attribute. Your cache Under the Bridge appears even more hazardous, as you are "luring" people to hike a knife-edged ridge which descends quite rapidly. Yet again, no "Dangerous Location" attribute. From your perspective, that sounds like a lawsuit in the making. Those of us (the collective us), with common sense recognize that simply being alive and interacting with the world involves risk. Because we recognize this, we take reasonable precautions when doing whatever it is we do, and accept responsibility for our injuries if we fail to take such precautions. Blindly walking from Point A to Point B would certainly qualify as failing to take reasonable precautions. Randomly select 100 caches. My guess is that at least 99 of them will be in locations where there exists the possibility for injury. I would further guess that those 99 will fail to mention the possibility for injury. Sounds like gross negligence to me... Knowing about a potential hazard and refusing to post warnings about it... Uh... Are there any states in this Union where the loser is always required to pay the winner's legal fees? If you don't mind, could you expound upon that pearl of wisdom? Since you appear ready to render a verdict, I can only assume you know all the facts of the case, as well as the applicable case law regarding each facet of the incident in question. Since you do know the facts, and presumably are not under the same gag order which the OP claims is keeping him silent, could you tell us what happened? As to Texas law not giving him a chance, can you explain that concept as well? If this case was resolved in the manner TGC claimed, it was settled out of court. The CO would have had to be a willing participant in such a settlement. How, exactly, did Texas law strip the CO of that particular right of due process?
