The purpose of Colorado Geological Survey’s (CGS) Hayden Gulch Quadrangle Geologic Map, Routt County, Colorado is to describe the geology, mineral and ground-water resource potential, and geologic hazards of this 7.5-minute quadrangle located south of Hayden in northwestern Colorado. CGS staff geologist David Noe and field assistants Michael Zawaski, Zachary Logan, and Daniel Hosler completed the field work on this project during the summer of 2010. The geologic map plates and the Authors’ Notes report reflects the conclusions made from field maps, structural measurements, photographs, and field notes generated by the investigators.

From the authors notes:
The Hayden Gulch 7.5-minute quadrangle is located in Routt County, Colorado, south of the town of Hayden (Figure 1). Steamboat Springs, the county seat of Routt County, lies 24 miles to the northeast. Craig, the county seat of Moffat County, lies 14 miles to the northwest. Hayden Gulch and the town of Hayden were named after Professor F.V. Hayden (1829-1887), geologist-in-charge of the Geological and Geographical Survey of the Territories, which explored and mapped this area of Colorado in 1874. The highest elevation in the quadrangle is on the Beaver Flat Tops (8,106 ft). The lowest elevation (6,660 ft) is where the East Fork Williams Fork River exits at the western border. A major bend in the river separates its upper reach, which flows northward from its headwaters in the Flat Tops mountain range, from its lower reach, which flows westward along the southern margin of the Williams Fork Mountains.
