Grasscatcher Posted October 28, 2015 Share Posted October 28, 2015 There is a USGS BM disk near the lower trailhead of Serpents Trail which is just inside the East entrance to the park. It is shown on Topo maps and the elevation is shown as 5058. On the BM is stamped "CC 12" and 5058 ft above sea level. (Set in 1934) I'm familiar with the difference in accuracy of "Scaled" vs "Adjusted" coordinates and elevations, and am just curious as to how accurate that elevation should be considered as being. Is there anywhere that a datasheet could be viewed on a BM like that? Near the upper trailhead for that same trail, there is a "Witness Corner" with the elev given as 5886.I'm looking for the "official" data on that one too. Thanks in advance for any info.
