+Student Camper Posted November 15, 2010 Posted November 15, 2010 I was reviewing some of the local benchmark finds and there is one(UV5583) that has two finds, including a photo each, One is dark and doesn't show enough detail to determine if it is correct, it may be, not an issue. The other find photo is clear enough to show that is NOT the right mark, close by about 1000 feet but incorrect. my concern is that someone else passing by on a cruise ship, as this probably was, may make this mistake again if they are using the photo as reference. I know this area well, I don't know if is something to be concerned about. Quote
Bill93 Posted November 15, 2010 Posted November 15, 2010 (edited) Unfortunately, it is quite common for somebody to see a disk and log whatever mark they see listed in the neighborhood, even though it isn't the one they found. Usually we just post a note after that log saying why it is wrong, and hope that others will see and heed the note. To go beyond that, you can send a polite email to the person who incorrectly logged it, but that doesn't always get it corrected. Edit: I didn't look at who else had logged it. I agree with NorthWes that I'd give a lot of weight to one of them who is a pro. Edited November 15, 2010 by Bill93 Quote

I could "find it" myself and make note of the error at that time, or, I could find it for myself and then log a note addressing the error. Either one would do the job? Quote
+NorthWes Posted November 15, 2010 Posted November 15, 2010 If I make a find where others have logged in error, unless I know the cacher I simply post my log as I feel it's correct (with photos - I'm so not able to validate accuracy months or years later on a 'find' when I don't have a photo) and let that stand in the log for the mark. If I know the cacher, I email them privately and discuss the issue before I post (much kinder to find out that way for whichever party ends up being in error). Navaids are tricky for several reasons - first and foremost is that the finder may have no experience with inland or coastal waterway navaids, and have absolutely no idea what they're seeing or should expect to see. I run a skiff in coastal waters in Prince Wm Sound, and have a copy of the Pacific Guide to lights & Navaids' appropriate section for the area I travel so I'm equipped to actually travel the coast and use the navaids. I've been to USCG small boat school where we had to learn to recognize what they mean. So, when I see a 'range light' or another odd description I'm pretty ready for what to expect. Secondly, although these were seen from a cruise ship, if you're an experienced compass/GPS user it's a snap to take a bearing on the navaid (which has adjusted coordinates) and be pretty sure that regardless of the angle of view you've got the right one. I'm inclined to think after viewing the photos and my charts for that area that the photos are of the correct mark. You - being 'on the ground' so to speak - can validate the finds by driving up to the navaid from the land side and confirming the background of the photos in question! I see the same several utility poles along the roadway, for example - but from different angles of bearing on the mark. And lastly, at least one of the prior finders is a pretty experienced surveying professional whom I trust would've gotten the mark right based on a bearing method. This is an excellent question - and for where you live one that is beyond the average cacher's opportunity & ability to observe as an action item. I primarily am concerned with making sure I get it right, and dont worry too much about other logs until I'm ready to compare my conclusions against them. If they differ, then I triplecheck my work to ensure it's not me in error (because too often it has been!) Quote

Thank you for your observations, on closer examination, spurred by your comment about an experienced surveyer, I find that the surveyer got it right as you might expect. The other mark in question is located on the end of the jetty at the Mountian Point boat ramp facility Next time I'm out in the boat,(come spring) I can duplicate both of those photos. Quote
CallawayMT Posted November 16, 2010 Posted November 16, 2010 Student Camper, Any of us can get one of these types of marks wrong. Without doing as was mentioned, getting right on the position to see what you see. I did definitely call out a few of these while on our cruise this year. I had to have NOT get too carried away with the legitmacy of these nav lights and even towers, gables and peaks due to the fact that their usefullness has basically expired as a surveying aid. I appreciate the vote of confidence from all due to my profession, but hey I was on vacation and I can guarantee I had a few Alaskan Amber's and Summer Ales while out on the deck. Kurt Quote
