History, geology, and environmental setting of selected mines in the upper Alamosa River Basin, Rio Grande National Forest, Conejos and Rio Grande Counties, Colorado

Describes the history, geology, and environmental setting of several mines in the upper Alamosa River drainage basin. All of the sites lie at least partly on U.S. Forest Service-administered land. The sites were selected by the U.S. Forest Service based on the results of an abandoned mine inventory completed by the Colorado Geological Survey. This information should be useful for developing reclamation plans for mines in the upper Alamosa River Watershed.
