Radiometric dating of samples from adjacent areas applicable to this quadrangle was performed by Harald H. Mehnert, U.S. Geological Survey. Technical reviews by Karl K. Kellogg and David A. Lindsey, U.S. Geological Survey, helped improve the quality of the geologic map, illustrations, and text. Sharon A. Smith graciously and painstakingly translated the map data into digital files. Carlos Vulgamott made preliminary digital copy of the map and cross sections.
The geologic map of the Hogback Mountain quadrangle provides new geologic information for public use and for use by governmental agencies for land-use planning, including assessment of natural resources, natural hazards, and recreational potential, and for land-use management. The map provides an interpretation of the complex geology and terrain to recreationalists using the Gates of the Mountains Wilderness. The map provides data for scientific interpretation of the geology of part of the south end of the Montana disturbed belt.
