Elevation: 1867.73 ft.
Designation: JOHN BROWNS GRAVE AZ 1942
Setting: Square Concrete Monument
Type: Azimuth Mark Disk
Year: 1942
Established By: NGS
Recovered: 06 August 2006
Rich and I recovered this azimuth mark as part of our recovery of PG0932, the JOHN BROWNS GRAVE tri-station. The azimuth mark is in good condition. We had some trouble finding it, as there is no longer a power pole 14 feet from the mark, and the scaled coordinates took us to a point just a bit too far south along John Brown Road. Once we walked just a few more yards north, however, we spotted the witness post and then the mark. See PG0932 for details and photographs.
A report on the condition of the station, both reference marks, and the azimuth mark was submitted to NGS, along with the following recovery note:
Recovered in good condition. The disk is an azimuth mark disk, not a reference mark disk. Power pole number 25-182 was not found in the vicinity. The witness post still exists. Autonomous (non-corrected) handheld GPS coordinates for the azimuth mark are 44 15 23.5(N) 073 58 25.6(W).
