Geology of the Bighorn Canyon Hardin area Montana and Wyoming : description of the geography stratigraphy structure geomorphology and mineral resources of the area
Richards PW. 1955. Geology of the Bighorn Canyon Hardin area Montana and Wyoming : description of the geography stratigraphy structure geomorphology and mineral resources of the area. Geological Survey Bulletin. (1026):I-93
This article describes the geology of an area of about 1,300 square miles in south-central Montana extending from Hardin, Mont., southward across part ofthe Great Plains to the Bighorn Mountains and thence southwestward through the mountains along Bighorn Canyon to the Bighorn Basin. This article was prepared as part of the Interior Department program for development of the Missouri River basin. The fourfold purpose of the investigation was (1) to map and study the terraces below the mouth of Bighorn Canyon in order to provide information as to the type of aggregate available for construction of the proposedYellowtail dam and show the distribution of terraces, some of which would be irrigated by water diverted from the Bighorn River by the dam; (2) to map the geology of Bighorn Canyon and show formations that would be covered in part by the Yellowtail reservoir; (3) to locate and describe mineral deposits of possible economic importance; and (4)to map and describe the rock formations, some of which contain known or potential oil-bearing strata elsewhere in Montana and Wyoming.
