资源简介：
This dataset was developed to provide a geologic map GIS database of Challis
1x2 Quadrangle, Idaho for use in spatial analysis.
The paper version of The geology of the Challis 1 x 2 quadrangle, was compiled
by Fred Fisher, Dave McIntyre and Kate Johnson in 1992. The geology was
compiled on a 1:250,000 scale topographic base map. TechniGraphic System, Inc.
of Fort Collins Colorado digitized this map under contract for N.Shock. G.Green
edited and prepared the Challis digital version for publication as a geographic
information system database. The digital geologic map database can be queried
in many ways to produce a variety of geologic maps.
