Description

Elaborate set of drawings relating to a proposed tunnel on "Favorite Vein," one of a group of maps and plats from a mining collection relating to La Plata County, Colorado.

Snow Slide Gulch, near Root Creek, appears on modern topographical maps in La Plata County and may be near Hollingsworth's Lost Mine.

Based upon the names of the claims, we date the map to circa 1890.

Spanish explorers who visited the La Plata Mountains in the 18th century may have found gold, but mining in the region did not begin until 1873 when placer gold was found along the Animas River near the present site of Durango. In that same year placer gold was discovered along La Plata River. Production during the early years in the La Plata district is not known, but it was probably small. Lode gold was also discovered in 1873, and by the end of 1881 many locations had been made.

The output from lodes was small through 1901, but with the discovery of new deposits in 1902, output increased sharply, and through 1914 annual gold production exceeded $100,000 (5,000 ounces).
