Geologic Map and Digital Data Base of the Almo Quadrangle and City of Rocks National Reserve, Cassia County, Idaho

June 24, 2008

This geologic map describes the geology of the City of Rocks National Reserve and environs, located in the Albion Mountains of south-central Idaho. The most prominent geologic features of the Reserve are the spectacular rock spires that attracted visitors, beginning with commentary in the journals of travelers to California during the Gold Rush of 1849. The tectonic history is outlined, and descriptions of landscape processes, a newly discovered Quaternary fault, and features of the pinnacles are presented.
