Geology and ground-water resources of the lower Bighorn Valley, Montana
Louis J. Hamilton, Q.F. Paulson
1968, Water Supply Paper 1876
The Bighorn River has incised a deep, broad valley in Cretaceous strata along its 65-mile lower reach below the mouth of Bighorn Canyon in south-central Montana. It ceased downcutting at six different levels 100-200 feet apart, widening its flood plain and alluviating each level with about 30 feet of sandy...

1968, Open-File Report 68-210
The geologic setting of the pyrite replacement deposit at Wadi Wassat was mapped in February 1966. From this mapping it is inferred that the pyrite deposits occur along a sub-vertical, north-trending fault in andesite and other rocks at the crest line of an anticline in a roof pendant. The pendant...

1968, Open-File Report 68-175
This paper is divided into two parts. Part I presents a review of some of the past uses of aerial photography in urban areas. The empirical studies reviewed are divided into two broad categories depending on whether inventory compilation is by direct or indirect observation. Studies using inventory by direct...
