Depth to the paralithic contact ranges from 20 to 40 inches.
Depth to effervescent horizons is 0 to 20 inches.
The particle-size control section has 35 to 75 percent rock fragments.

COMPETING SERIES: These are the Ellena, Elve, Hiore, Millswitch, Pergrin, Rubick, Scout, Shadow, Taglake, and Vandamore (CO) series.
Ellena, Vandamore - have lithic contacts above 40 inches
Elve, Hiore, Millswitch, Rubick, Scout, Shadow, Taglake - do not have paralithic or lithic contacts above 40 inches
Pergrin - has granite rock fragments
GEOGRAPHIC SETTING: Danavore soils are on mountainsides and hillcrests. Slopes range from 5 to 30 percent. The soil formed in slope alluvium over residuum derived from interbedded sandstone and shale. Elevation ranges from 7,200 to 8,600 feet. The mean annual precipitation ranges from 15 to 20 inches. Mean annual temperature ranges from 37 to 40 degrees F. The frost-free period is about 45 to 75 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cochetopa, Jerry, Rhone, and Waybe soils. The Cochetopa, Jerry, and Rhone soils are deep and have mollic epipedons. The Waybe soil is shallow to bedrock.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderate to moderately slow permeability.
USE AND VEGETATION: These soils are used for livestock grazing and wildlife habitat. Native vegetation consists of bluebunch wheatgrass, bottlebrush squirreltail, Sandberg bluegrass, prairie junegrass, and black sagebrush.
DISTRIBUTION AND EXTENT: Danavore soils occur in northwestern Colorado. The series is of small extent. Total area in Moffat and Rio Blanco counties is about 2,100 acres.
