Permit M-1977-493—Climax Mine Technical Revision 37 (TR-37)
Cliffs and Talus
No soil is associated with this inclusion. Limited by steepness, and surface roughness that
includes loose rock and rock outcrop exposures.
SOIL PROPERTIES AND QUALITIES
Leadville
Landform:
Parent Material:
Effective rooting depth: greater than 20 inches.
Natural drainage class: well.
Depth to seasonal high water table: greater than 6 feet.
Available water capacity: moderate.
Permeability: moderate.
Runoff: moderate.
VEGETATION
Potential natural communities:
Leadville: subalpine fir-Engelmann spruce/Rocky Mountain whortleberry (Abla-Pien/Vamy2)
below 11,000 feet and subalpine fir-Engelmann spruce/grouse whortleberry (Abla-Pien/Vasc)
above 11,000 feet.
USE AND MANAGEMENT CONSIDERATIONS
Major uses: timber harvest, dispersed non-motorized recreation, wildlife habitat and watershed.
Mass movement potential:
Landslides: low.
Debris flows: low.
Snow avalanche: low.
Road and trail limitations:
Cut and fill slope stability
Leadville: moderate -slope.
Improved unsurfaced roads:
Leadville: severe -slope.
Offroad vehicle roads and trails:
Leadville: severe -slope and erosion hazard.
Foot trails and paths:
Leadville: moderate -slope.
Revegetation Limitations:
Leadville: moderate -slope and erosion hazard.
Revegetation Considerations: Mulch will conserve soil moisture and protect seedling
establishment. Surface netting in conjunction with mulching will reduce the erosion hazard.
Timber Management Considerations: Harvest is limited by slope and erosion hazard.
Wildlife Management Considerations: This map unit provides shelter for upland game
animals.
Acid precipitation buffering capacity: moderate.
