File Structure:

GIS data compressed into GIS_data.zip

	/export/ (ESRI export format [.e00] files for vector geologic data layers. Prefixes listed below applay also to 	the shapefiles) 
		bedrock (polygon layer of bedrock geologic units)
		crypto (point layer of cryptozooan chert locations [see text on plate])
		drillholes (point layer with location of drillholes, small karst features, and cataclastic shears)
		faults (line layer with faults)
		points (point layer with measurement data for bedding and joints)
		resid (polygon layer delineating areas of QTrr map unit)
		sinks (polygon layer delineating sinkholes)
		strux_cont (line layer with structural contours for the elevation of the base of the Roubidoux 				Formation)
		surf (polygon layer delineating areas of surficial units Qa and Qt)
