Benchmarks, survey markers, and maps

[edward]

@DAW89946, @MojaveGeek: Thank you for the replies!

Thanks for pointing me in the direction of the various types of corners. (I found the definitions here.) This marker seems to be in the center of a section rather than on a corner, but maybe I am reading the maps incorrectly.

And thanks for pointing me to the PLSS. Although I'm still trying to decode this on the maps I've seen, this part of the Owlsheads are just at the northern part of San Bernadino County. The following image (lifted from Wikipedia's article) on the PLSS, shows grids with perfect squares:



I guess that "S36" on this marker has something to do with Section 36. The weird thing on the Peakbagger map of that area is that there are two sections just south of Lost Lake that are labelled 36, one right above the other. (BTW: I am not sure how to find the original 7.5 minute quad on CalTopo or USGS. I don't expect anyone here to spend time being my tutor, however, I would be grateful if anyone has a link.)

Thanks again!
