SOIL MAPPING UNIT - COUNTERS-TRAVESSILLA COMPLEX
•
LTE - Louviers-Travessilla complex, 3 to 25 percent slopes. This map
unit is on ridges and side slopes. The native vegetation is mainly
pinyon and juniper. Elevation ie 6,300 to 7,500 feet. The average
annual precipitation is 14 to 16 inches, the average annual air
temperature is 48 to 54 degrees F., and the average frost-free period is
100 to 130 days.
This unit is about 45 percent Louviers very channery clay loam and about
35 percent Travessilla channery sandy loam. The Louviers soil is oa
side slopes, and the Travessilla soil is on ridgetopa.
Included in this unit is about 15 percent Noden loam in drainageways and
on foot slopes. The Noden soil is deep. Also included are small areas
of sandstone Rock outcrop on the steeper side slopes.
• The Louviers soil is shallow and well drained. It formed is residuum
derived dominantly from clayey shale. Typically, the surface layer is
brown very channery clay loam about 3 inches thick. The substratum is
shaly clay loam about 13 inches thick over soft shale at a depth of 16
inches. The soil ie neutral.
Permeability of the Louviers soil is slow. Available water capacity is
very low. Effective rooting depth is 10 to 20 inches. Runoff is very
rapid, and the hazard of water erosion is very high. The Travessilla
soil is shallow and yell drained. It formed in residuum derived
dominantly from sandstone. Typically, the surface layer is light
brownish gray channery sandy loam about 6 inches thick. The substratum
is channery sandy loam about 9 inches thick over sandstone at a depth of
15 inches. The soil is mildly alkaline to a depth of 6 inches and
moderately alkaline below that depth.
Permeability of the Travessilla soil is moderately rapid. Available
water capacity is very low. Effective rooting depth is 6 to 20 inches.
