This SRTM 30m elevation overlay shows 100' lower elevations than 10m DEM data. SRTM data was collected in 2000 and shows the results of strip mining in the area.
☹ Sadly, the microsoft terraserver (MSTopo) USGS topo map server is no longer active. The MSTopo had a higher resolution topo and was the base layer for the google map above. To zoom in try selecting the ArcGIS topo base map.
The grid of elevation points is based on older generations (e.g., 2009) of USGS 10M DEM data. See naionalmap elevation data.
