Soil Summary:

dominant soils are shallow to moderately deep to bedrock, very flaggy and flaggy loam and gravelly fine sandy loam surfaces over very channery sandy loams clays and very gravelly fine sandy loams, no lime present, weak to strong development; unit dominated by Pima County soil survey map units 77 (Spudrock-Lemmon complex, 15 to 45 percent slopes) and 76 (Spudrock-Far-Rock outcrop complex, 25 to 65 percent slopes). These units comprise 97% and 2% of the ELT, respectively

Geologic Materials:

alluvium, colluvium and residuum associated with the Catalina-Rincon igneous metamorphic complex (TXm) comprises 100% of the unit

Landforms:

moderately dissected, moderately incised mountain slopes (especially lower two-thirds of the unit)

Land Type Association: LTA 13

Ecological Unit: Madrean pine-oak forest/woodland on mountains derived from granite, gneiss, and similar rocks
