LOCATION HEINERS UTEstablished Series
TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid, shallow Typic Haploxerepts
TYPICAL PEDON: Heiners gravelly loam, on a west facing convex, 7 percent slope in rangeland at an elevation of 7,250 feet. (Colors are for moist soil unless otherwise noted.) When described on September 21, 1976, the soil was dry throughout.
The surface is covered by 20 percent gravel.
A1--0 to 3 inches; dark reddish brown (5YR 3/4) gravelly loam, brown (7.5YR 4/4) dry; moderate fine granular structure; soft, very friable, slightly sticky and slightly plastic; many very fine and fine roots; few fine vesicular pores; 20 percent gravel; strongly effervescent; carbonates are disseminated; moderately alkaline (pH 8.4); abrupt wavy boundary (1 to 4 inches thick).
A2--3 to 8 inches; reddish brown (5YR 4/4) gravelly loam, brown (7.5YR 5/4) dry; weak and moderate medium subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; common very fine and fine roots; common very fine and fine tubular pores; 20 percent gravel; strongly effervescent; carbonates are disseminated; moderately alkaline (pH 8.4); clear smooth boundary (3 to 7 inches thick).
Bw--8 to 12 inches; yellowish red (5YR 5/6) very gravelly loam, reddish yellow (5YR 6/6) dry; moderate medium subangular blocky structure; hard, friable, slightly sticky and slightly plastic; common very fine and fine roots; common very fine tubular pores; 35 percent sandstone gravel; strongly effervescent; carbonates are disseminated; strongly alkaline (pH 8.7); clear smooth boundary (4 to 6 inches thick).
C--12 to 19 inches; yellowish red (5YR 5/6) very gravelly loam, reddish yellow (5YR 6/6) dry; massive; hard, friable, slightly sticky and slightly plastic; common very fine roots; few very fine tubular pores; 55 percent sandstone gravel; strongly effervescent; carbonates are disseminated; strongly alkaline (pH 8.7); clear smooth boundary (0 to 8 inches thick).
Cr--19 inches; weathering sandstone bedrock.

GEOGRAPHIC SETTING: Heiners soils.
Parent material: Residuum, colluvium and slope alluvium derived from sandstone, conglomerate and shale.
Landform: Mountain slopes
Slopes: 4 to 70 percent
Elevation: 5,400 to 8,000 feet
Mean annual air temperature: 40 to 45 degrees F.
Mean annual precipitation: 14 to 16 inches.
Wettest months: March through May
Driest months: July through September
Frost-free period: 70 to 100 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Echocreek,
Fewkes and Richsam series.
Echocreek: Very deep soils on fan remnants along drainageways
Fewkes: Very deep soils on mountain slopes
Richsum: Deep soils on mountain slopes
