MAHAN Azimuth (DH2478) - Brierfield, AL - Azimuth Benchmarks on Waymarking.com

After caching in Brierfield Ironworks Park, we headed for this benchmark using the description from the datasheet. While the triangulation mark was on private property, the azimuth was listed as being on the right of way. Driving along West Ashbury, we spotted the witness post along the fence line. After parking and making our way to the spot, we poked around until we hit something solid. We dug out the concrete and then cleaned the mark as best we could so we could take pictures. The coordinates are the ones we took at the mark, not the ones on the datasheet for the triangulation station.

The description from the datasheet reads:
