资源简介：
The conversion of bedrock geology information of the park
into a digital format enables easy overlay with other layers
for analysis and development of other themes.
The bedrock geology coverage was developed from the 1972 USGS
Geologic Map of Yellowstone National Park. It shows polygons
of bedrock formations. Attributes attached to each polygon
include a formation code, formation name, formation age, and
a generalized formation name. These data are unpublished material.
