LaGrange Mine (Hydraulic)

Trinity County · Approximately 4 miles west of Weaverville · location approximate

This mine, originally known as the Oregon Mountain Group of Claims, first operated about 1862. In 1892 the mine was purchased by the LaGrange Hydraulic Gold Mining Company which brought water from Stuart's Fork through 29 miles of ditch, tunnels and flume and delivered it to the mine pit under a 650-foot head. Over 100,000,000 yards of gravel was moved and $3,500,000 in gold produced. Large-scale operations ceased in 1918.

1971 register text, presented as a historical document. It uses the period's terms for Native people; the state's landmark listings still carry most of this wording, and the California Office of Historic Preservation maintains the program's current texts.

Many of these plaques have since been recast or their texts revised. The California Historical Landmarks program and its current texts are maintained by the California Office of Historic Preservation. California Office of Historic Preservation ↗
