COMPETING SERIES:
The
Lumpyridge soils are very deep.
GEOGRAPHIC SETTING: Lininger soils are on mountain slopes and have slopes of 1 to 65 percent. Elevations range from 6,500 to 8,500 feet. The soils formed in weathered schist, gneiss, and granitic rocks. The soils are in a cool semiarid climate with annual precipitation ranging from 18 to 22 inches. The mean annual temperature is about 41 to 46 degrees F. The frost-free season is about 75 to 125 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Breece, Hesperus, and Ratake soils and Trag soils. Hesperus and Breece soils have a mollic epipedon more than 16 inches thick. Ratake soils have bedrock at depths less that 20 inches. Trag soils have lack a paralithic contact above 40 inches.
DRAINAGE AND PERMEABILITY: Well drained; slow to medium runoff; moderate permeability.
USE AND VEGETATION: Soils are used for grazing, hayland, recreation, wildlife, and community development. Native vegetation is Arizona fescue, mountain muhly, Parry oatgrass, wax currant, mountain mahogany, sticky geranium, fringed sage and sulfur buckwheat. In places where surface layers are stony, scattered ponderosa pine trees are common.
DISTRIBUTION AND EXTENT: Mountainous areas of north-central Colorado and southern Wyoming. The series is of moderate extent.

Taxonomic Version: Eighth Edition, 1998
The mineralogy class was changed from paramicaceous to micaceous in 07/2010 by the National Soil Survey Center on request of the responsible MLRA regional office. The change was necessary based on the eleventh edition of the Keys to Soil Taxonomy, 2010.
