Report on the Geology of the Henry Mountains

Report on the Geology of the Henry Mountains, published in 1877 by Grove Karl Gilbert, is a scientific examination of the geological structure of the Henry Mountains in Southern Utah, based on field studies conducted in 1875 and 1876. The report details the unique geological formations, rock series, and processes of uplift and erosion in the region. Gilbert introduces the concept of laccolites, which are masses of igneous rock that intrude into other rock layers, highlighting their significance in understanding the area's geological history. This work is notable for its thorough exploration of a previously unexplored region and its contributions to the field of geology.
