COMPETING SERIES: These are the Demar and Thurlow series. Demar soils have early summer moisture peaks. Thurlow soils are very deep.
GEOGRAPHIC SETTING:
Parent material: alluvium and residuum derived from sandstone and shale
Landform: hillslopes, structural benches
Slopes: 1 to 55 percent
Elevation: 6,950 to 7,650 feet
Mean annual temperature: 45 to 52 degrees F
Mean annual precipitation: 15 to 18 inches
Precipitation pattern: Precipitation falls year round but peaks in July and August, and declines in spring. April, May, and June are the driest months. Total snowfall averages about 4 to 5 feet with snowmelt lasting through April.
Frost-free period: 100 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Menefee, Orlie, and Vessilla series. The Menefee soils are shallow, do not have argillic horizons and are on shoulders and upper hillslopes . The Orlie soils are very deep, have less clay and are on valley sides. The Vessilla soils are shallow to hard sandstone and are on ridges and hillslopes.
DRAINAGE AND PERMEABILITY: Well drained, rapid runoff, slow permeability.
USE AND VEGETATION: The major uses are livestock grazing and wildlife habitat.
DISTRIBUTION AND EXTENT: North central New Mexico; RM-2 subresource area, MLRA 36 The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana
SERIES ESTABLISHED: Rio Arriba County, New Mexico, Jicarilla Area, Parts of Rio Arriba and Sandoval Counties Soil Survey. The name Teequee is taken from a nearby canyon.
