资源简介：
The paper version of The geology of the Challis 1°x2° 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.
