Most of my pictures are close up shots of some cool ones or dismal scenery pointing to reference marks. My best 2: CG0359CH5701

While we can still submit logs to the NGS, all of the previous data from the benchmarks people have logged on the geocaching website will be lost to time.

If you guys want to try and preserve some of your favorite pages, use the internet archive: https://chrome.google.com/webstore/detail/wayback-machine/fpnmgdkabkmnadcjpehmlllkndpkmiak (Chrome extension) Make sure to check the "Outlinks" checkbox so photos are saved. You can only be saving ~2 pages at a time.

While that may have been the first benchmark, the first survey disk was likely from 1898, looking into it. (https://pubs.usgs.gov/circ/1341/pdf/circ_1341.pdf pg. 47 (pdf pg. 73)) I have only identified ones as old as 1899 so far. HS4920 https://www.geocaching.com/mark/details.aspx?PID=HS4920 (There was an iron post here predating the mark) DU2280 https://www.geocaching.com/mark/details.aspx?PID=DU2280

The actual oldest disk that I have ever found was monumented in 1903 by the USGS. CZ1865 The NGS datasheet says otherwise but the USGS datasheet (page 4) says it was placed in 1903. It references TORTOLLITAS, which has been presumed destroyed by an experienced backcountry benchmark searcher. TORTOLLITAS references WASSON. WASSON has no references meaning it is the oldest disk in the Tucson area. I have been up to the peak twice but I had no idea the USGS mark was 1 foot underground according to the USGS datasheet (page 8), which I only found out making this post. I now plan to go back up here and see if I can find this piece of history. One that I haven't found but is there is ET0979 which was monumented in 1902 which is likely there claiming the oldest one that I found documented as there recently. http://surgent.net/highpoints/az/mobile/weaver_m.html
