Is there a way to find the elevation of the BLM monument in the attached photo? Or does BLM not track or provide that info? It does not appear to be at a section boundary.
Thanks!
That looks like a mineral survey corner.
No, BLM doesn't care about elevations, unless they are surveying a boundary that is dependent on elevation.?ÿ
That looks like a mineral survey corner.
I was thinking the same thing Dave.
Yeah, it looks like a witness corner to a mill site.?ÿ Survey number is 4?76B, with the ? being either a "3", "8" or "9" (my guess is "3").?ÿ
If you are looking for a reliable elevation, you most likely need to look elsewhere.?ÿ It may be that in 2017 the BLM conducted the survey with GPS and there is a geodetic position for this shiny new brass cap.
In Colorado, the BLM will sometimes prepare a GPS Corner RecoveryLocation Card for a found corner.?ÿ The examples I've seen have lat/long/height.?ÿ On one card the height was reported to the nearest 0.1 ft., but I have no idea if that is an ellipsoid height or an elevation.?ÿ The card states it was an RTK observation and this is below the lat/long/height values, "NAD83 (2011)", which indicates the horizontal datum was NAD83 (NSRS2011).
