资源简介：
This quadrangle lies 6.4 km (4 mi) northeast of Bozeman, Mont., in
southwestern Montana. Metamorphic, sedimentary, and volcanic rocks
of Precambrian to Tertiary age are exposed in the Bridger Range and
southwestern margin of the Crazy Mountains Basin in a crustal cross
section and a structural triangle zone. Surface geology records
Precambrian extension, Late Paleocene east-vergent contraction,
including backthrusts, and Holocene basin-range extension.
