NORTH SIX-SHOOTER CREEK
General Description: This northwest view of Sixshooter Peak was taken
from a mid-shelf of South Sixshooter Peak. The area is public land administered
by the Bureau of Land Management.
Soils: Two soils are found in the valley between Sixshooter Peaks. Soils
on the far side of the mid-scene drainage area consist of Thoroughfare very deep
(over 60 inches) alluvium derived primarily from red sandstone. This specific
soil is a well drained fine sandy loam. Soil on the near side of the drainage is
a Moenkopie-rock complex. Moenkopie soils are gravelly loam sands derived from
sandstone. They are well drained and shallow, ranging from 3 to 20 inches to
bedrock.
Precipitation: Thirty three years of precipitation records taken at
Canyonlands National Park some 5 miles west of this location indicates an
average annual precipitation rate of 8.40 inches.
Legal Description: NW1/4NE1/4 Section 6 T.31S., R.21E.
COMPARISON: Little appreciable change is apparent when comparing the 1927
and 1999 images. The ephemeral drainage has narrowed and is somewhat more
vegetated. Harsh soil conditions and limited precipitation combine to limit
vegetation development potentials here. Moenkopie derived soils are not
conducive for grass production. Plant species present include blackbrush,
shadscale, Mormon tea, fourwing saltbush, snakeweed, Indian ricegrass,
curlygrass and cheatgrass. A few additional juniper trees have established since
1927.
