Intrigued by the dichotomy of search results, I did a little research to find that CASEY ROAD was the original name for this section of Curtner Avenue, so I think the bridge used to be where the footbridge is now. I thought that might explain the varied results, since the posted coordinates would make you think they're talking about the Camden Bridge. So I searched around the footbridge but found no disk and, in fact, nothing that looked remotely old enough to be part of an old road bridge from 70 years ago. Too bad the people reporting finds didn't give us any clues about what they found or where they found it.

Just happened upon this one while out on the LCT!

Also note not found by NGS in 1990.

The area here has been repaved and reworked, the curbs and wing walls look to have been re-done on both sides of San Tomas here. It's gone, or I missed it. :)

Did not find it. 50sumtin

Found this one along the LG Creek Trail, mostly by pure coincidence of being there!

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
  • The geoid height was determined by GEOID99.
