The primary source for this data layer is a 1973 map at 1:1,000,000scale published by the WGNHS and USGS. Where more recentinformation was available, the USGS updated the 50-foot and100-foot contours of the depth-to-bedrock map at a scale of1:250,000. Soil associations data, and other information, wereused to add a 5-foot contour to the data layer.
