Checked my GPS elevation reading with a benchmark
There is a surveyor's benchmark next to the Parkway, and on my way back, I stopped to read the elevation at that point. The BM said 4314 feet. My GPS said 4344 feet. Considering that my GPS is an old three-satellite device, the 30 foot discrepancy is ok.
