Eaglehaslanded Posted August 21, 2005 Share Posted August 21, 2005 I geust this will be a two part question. I just came back from Hatteras. While I was there I did some caching and benchmark hunting. I went hunting for EX0345 which is Cape Hatteras LH 1933. A lot of people have logged this one. For GC I see this as ok, but it is the wrong location. On the NGS datasheet the recovery note logged by USPSQD states EX0345'COORDINATES MOVED TO N35 15 08 W075 31 44 BY EXECUTIVE OFFICER USCOAST GUARD GROUP CAPE HATTERAS Should this be recoved as not found? All reference marks are DESCRIBED IN ORIGINAL DESCRIPTION from the original LH location. Let me know what you think Brian Quote Link to comment
+Black Dog Trackers Posted August 21, 2005 Share Posted August 21, 2005 Benchmark hunting is about finding the mark in its surveyed location. The PID should be logged as destroyed on the geocaching site. If you wish to report to the NGS, email Deb with pictures and documentation supporting a decision to mark the PID as destroyed.

+seventhings Posted August 21, 2005 Share Posted August 21, 2005 BDT is correct. I would log EX0345 as DESTROYED on Geocaching. Then, I would do an NGS recovery report as NOT FOUND with the explanation that the lighthouse no longer occupies the location of the published coordinates. Then, I would send an e-mail to Deb Brown with an explanation an a few photos, and I would recommend that NGS reclassify the station as DESTROYED. After the NGS datasheet reflected the new (destroyed) status, I would go back to the Geocaching datasheet and update my log to reflect the fact that the station was destroyed and that the destruction pre-dates the numerous FOUND IT logs. Of course, this is just a game and all that I suggest, above, is optional. w Quote Link to comment
ArtMan Posted August 21, 2005 Share Posted August 21, 2005 And that was a hell of a moving job. This web page discusses the moving of large objects, including the Hatteras lighthouse, comparing the job to techniques used by the ancient Egyptians! -ArtMan- Quote Link to comment
Eaglehaslanded Posted August 23, 2005 Author Share Posted August 23, 2005 Thanks for everyone's input. I think I will log it as suggested. Brian Quote Link to comment
evenfall Posted August 23, 2005 Share Posted August 23, 2005 Seven is correct. The survey data is more about the position than it is about the lighthouse. This is true of any survey mark. If the position is moved, it is no longer the position. This renders the data bad. Destroying a landmark's position is something NGS has little problem doing as they have little control over landmarks like these. Positional accuracy is the highest priority. This station is destroyed, and since it was a landmark third order station NGS will likely destroy it too. I would send Artman's link as supporting evidence to deb.brown@noaa.gov and ask that the lighthouse be considered a destroyed survey mark, as it no longer occupies it's original location. Good Luck!

ArtMan Posted August 23, 2005 Share Posted August 23, 2005 My recollection is that the reason the lighthouse was moved is that the steadily eroding beach would have resulted in the demise of the lighthouse one of these years. So the station was going to be destroyed anyway; at least this way, they saved the lighthouse. -ArtMan- Quote Link to comment
+Harry Dolphin Posted August 24, 2005 Share Posted August 24, 2005 Definitely include Artman's link! NGS loves supporting documentation! That's how I managed to get a disk listed as destroyed! And we know how NGS hates to list disks as destroyed! KU1430, with this Ruppert Towers as supporting documentation. The Hatteras Lighthouse no longer serves as a benchmark. It has been moved. Destroyed is the proper option. Quote Link to comment
Eaglehaslanded Posted August 24, 2005 Author Share Posted August 24, 2005 I just sent my email to Deb Brown recommening EX0345 be changed as DESTROYED. Lets see what happens !! Brian Quote Link to comment
evenfall Posted August 24, 2005 Share Posted August 24, 2005 Good Luck Brian and thank you for your work on this. Best Regards, Rob Quote Link to comment
Eaglehaslanded Posted September 1, 2005 Author Share Posted September 1, 2005 I just checked back on EX0345 Cape Hatteras Lighthouse and it is now listed on the NGS site as destroyed. Thanks for everyone's input on this matter. Brian Quote Link to comment
