California Specific Benchmark Question in Benchmarking Posted May 9, 2012 Hello CaliCoe, Did you ever find out what the deal was with that benchmark? I found one recently at Big Basin Redwoods State Park at N 37 10.522' W 122 13.972' that I'm having trouble finding information on (or any information on California-specific benchmarks in general). Here's what I know: Coordinates -- N 37 10.522' W 122 13.972' Altitude (as reported by my GPS) -- 1264 ft Markings -- L.S. 2716 S 6 1/4 --|-- 1 S 7 L.S. 2716 While hiking in a local state park (Henry W. Coe) I saw a survey marker just off the trail set in a concrete footer. I took a photo (sorry, it was a real photo not digital and thus not on my computer). It was marked "California Dept of Parks & Beaches" with the year 1966 and the designation F-5 stamped into it. I read the FAQ on benchmarks that aren't on the website, so I just wanted to share this info with everyone. I'm hoping someone can give me some history on these benchmarks and maybe a little about the old department of Parks and Beaches. I'll try to get the phot scanned, but until then, for those who are interested, the location is: N37°10.934 W121.31746 I believe the mark pictured above is a Public Land Survey System marker placed on the boundary between Section 6 and Section 7 of 9S 3W. (This would be referred to as a "quarter corner" marker as it is halfway between two section corners.) Here's an image to show what I found: And that mapping system is accessible here: http://www.geocommunicator.gov/GeoComm/lsis_home/home/ Under Interactive Maps/PLSS More info on the PLSS in general can be found here: http://en.wikipedia.org/wiki/Public_Land_Survey_System As for the other one mentioned in here, a picture would be helpful, but taking a guess based on the coordinates (which I assume were supposed to be N37 10.934' W121 31.746 not W121.31746) and say that it might have been placed as a park boundary marker. Thanks, EdrickV!
