Purpose: This grid was created to facilitate locating mines and geologic features in the GMUG study area. Supplemental_Information: The grid was created in MapInfo Professional version 5.0 using the standard grid building tool. Each of the quadrangle names was typed into the newly created database in MapInfo's browser window. The resulting "map" was printed and manually compared to the USGS index to topographic maps.

No accuracy determinations have been made. Completeness_Report: The data are considered complete for the locating 7 1/2- minute quadrangle maps in the rectangular study area from 106 to 109 degrees west, 37.75 to 39.5 degrees north. Logical_Consistency_Report: The data set was derived using a MapInfo tool. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: It is assumed that the corners of the quadrangles are accurately calculated and displayed at scales as large as 1:24,000.
