Summary

The primary objectives of the Little Bear Mine Reclamation Project were to:

  1. Facilitate proper drainage of effluent from the Little Bear Mine adit;
  2. Prevent and remediate serious erosion problems at the site; and
  3. Restrict damaging vehicle recreational use on the site.

The Little Bear Reclamation Project was a Cooperative Project between the Arapaho & Roosevelt National Forests Abandoned Mine Lands Program and the Clear Creek Watershed Foundation. Construction involved removal of a nonfunctional drainage pipe which had been installed to convey mine drainage to Little Bear Creek. 

This pipe had been crushed due to recreational vehicle use of the area. The pipe was replaced by an open drainage channel (6 feet wide by 3 foot deep and lined with cobble-sized rock), which was designed to facilitate runoff from the adit to Little Bear Creek. Large boulders were placed along Co. Road 155 at the culvert crossing to Co. Road 140 used to remove access of vehicles on the site. In addition, the ground surface from bedrock to Co. Road 155 was rendered into an uneven and hummocky condition to deter any recreational camping around the site. Extra rock and slash was scattered across this area to provide micro-communities to assist in revegetation. Seed was broadcast across all disturbed areas and raked in to the surface soil.
