slidegear Posted January 30, 2008 Share Posted January 30, 2008 (edited) bagged my first benchmark when i took a couple of friends for a fly over maui... remember seeing the disk on the side of the volcano but couldn't remember what they were called. took a few pictures and forgot about it till now! sure gonna be tough to top that one.

Wintertime Posted January 30, 2008 Share Posted January 30, 2008 What a fun location to find a benchmark! Do you have any photos of the location you could post? I bet they're pretty! I've never been to that part of Maui. One clarification: the mark you found is actually TU2939. See the arrow and the "NO. 1" on the disk? Those mean that it's a reference mark. According to the descriptions at the bottom of the page for TU2940, the main benchmark (TU2940) is about a foot away from RM1, beneath a platform (if it's still there), and about four inches below ground level. Maybe it's in one of your other photos? So, do we have you hooked now? Patty Quote Link to comment
mdg2003 Posted January 30, 2008 Share Posted January 30, 2008 (edited) I predict slidegear will be smacking himself on the forehead with an open palm....How far is Maui from Chicago? Edited January 30, 2008 by mdg2003 Quote Link to comment

Patty ooops... guess i didn't have it after all! my bad, thank you for the correction patty... i'll have to see about amending the error. reading the history indicates that the original concrete post probably doesn't exist any more. the platform is still there but i seem to remember that you could access beneath it from a cutaway on the top and all around at least two of the sides (guess i might have been real close after all). saw the RM1 disk's description after looking around for a reference for so long that it made me jump to that conclusion haste. had a feeling that there was more too it than that. the location is beautiful, it is a cow pasture where the mountain drops off into the sea far off in the distance. there is a large concrete platform at that spot about two or three inches thick set about thigh high but otherwise no other signs of civilization. my other shots do not give the location any justice (i was more interested in the disk and platform) but i'll see if i can grab some frames off of the video a friend took of the flight.

68-eldo Posted January 31, 2008 Share Posted January 31, 2008 This picture is of a type a Hawaii Territory Survey Triangulation Station Monument. Did the platform look like that? Sorry I could not find a better picture. The mark is usually directly below the pole in the center and difficult to photograph. This is designed to allow a surveyor to remove the pole and occupy the mark. You can sometimes photograph the disk that way. Quote Link to comment
Wintertime Posted January 31, 2008 Share Posted January 31, 2008 ooops... guess i didn't have it after all! my bad, thank you for the correction patty... i'll have to see about amending the error. You did a great job of explaining everything on both the TU2939 and TU2940 pages here on Geocaching.com. The photo of your tour group is very cute, too! reading the history indicates that the original concrete post probably doesn't exist any more. the platform is still there but i seem to remember that you could access beneath it from a cutaway on the top and all around at least two of the sides (guess i might have been real close after all). This history of this station is very confusing! Post, pier, platform, tablet, monument, target...I wonder whether it's standard procedure to put on a reference mark the date of the original station to which the RM is pointing, not the placement date of the reference mark itself. (In this case, 1929 vs. 1965.) Maybe someone else here can jump in and confirm where exactly you should look for the bronze HTS disk if you ever get a chance to go there again.

slidegear Posted January 31, 2008 Author Share Posted January 31, 2008 i seem to remember a number around 4,490 miles mdg2003 but i can't remember where orwhen i saw it. the platform is similar but of different proportions 68-eldo. it was set into a pedestal of pier-like construction. there is a post with a target marker and some evidence of some minor disturbance to the site. i didn't think of (re)moving the post but then again i didn't know what i was looking for. in retrospect i would still refrain from doing so should i encounter a similar situation to this one. btw wintertime... here's how we got there. notice the spot on their map?

This one is a reconstructed “platform”. Because of all the construction in the area this one has been renovated. But the signal remanins the same. Quote Link to comment
68-eldo Posted February 1, 2008 Share Posted February 1, 2008 If you look at my recovery of Gilbert there are pictures of the “tablet” under the signal pole. It is at or near ground level and the cross bar above the tablet is to prevent the post of the signal from contacting the mark. With the pole removed the surveyor can drop his plumb-bob down to the mark while the platform provides a location for the tripod. The signal on this one is gone for some reason. This location has been out in the middle of a cane field for many years. Now “civilization” is moving in on it. Quote Link to comment
CallawayMT Posted February 13, 2008 Share Posted February 13, 2008 I was able to get to a few different type while on Kauai within the last two weeks: POOKU=HANALEI LATITUDE STATION RESET CANYON B HITS 1967 Pele Reset A lot of fun finding these marks, but the environment and vegetation is brutal on this island.

foxtrot_xray Posted February 13, 2008 Share Posted February 13, 2008 Those look SO FREAKIN' COOL. I finally have a reason to want to go to Hawaii. (Just kidding.. I have a lot of reasons to go.. now I have more.) Quote Link to comment
+89SC Posted February 14, 2008 Share Posted February 14, 2008 They are cool and should be much easier to find than a disk in a rock on a mountaintop like around here. Quote Link to comment
68-eldo Posted February 14, 2008 Share Posted February 14, 2008 I knew I had this picture someplace. It's Gilbert occupied Quote Link to comment
