Geology

Coalmont, Colorado, is the type locality of the Coalmont Formation. [6]

Mining history

Coalmont was a mining town associated with the production of coal from the Coalmont Coal District. In the Coalmont Coal District, commercial coal mining from the Coalmont Formation started in 1909 and continued until the close of World War II when coal production ceased. Since then, the mines were inactive, until 1959 when a new open pit mine was opened and some coal was mined and sold in the Denver, Colorado area. However, coal mining ceased a year or two later and there has been no production of coal since that time, despite some coal prospecting in 1964 and 1965. The estimated coal production in 1941 was 1,438,355 tons, and the original reserves at 177,450,000 tons of subbituminous coal. [6] [7]

Potosi Peak is a 13,786-foot-elevation (4,202-meter) mountain summit located in Ouray County of Colorado, United States. It is situated five miles southwest of the community of Ouray, on land managed by Uncompahgre National Forest. It is part of the Sneffels Range which is a subset of the San Juan Mountains, which in turn is part of the Rocky Mountains. It is situated west of the Continental Divide, 2.2 miles south of Whitehouse Mountain, and 2.5 miles southeast of Mount Sneffels. Potosi ranks as the 113th-highest peak in Colorado, and the fourth-highest in the Sneffels Range. Recreation enthusiasts heading for Yankee Boy Basin traverse below the southern base of the mountain. Topographic relief is significant as the southeast aspect rises 4,000 feet above the Camp Bird Mine in approximately 1.5 mile. The mining activity in the immediate area produced significant amounts of gold and silver. "Potosi" in Quechuan language translates to "great wealth.". The mountain's name, which has been officially adopted by the United States Board on Geographic Names, was in use before 1899 when Henry Gannett published it in A Dictionary of Altitudes in the United States.
