brown (2.5YR 4/4) moist; weak fine
granular and weak medium subangular
blocky sttucture; slightly hard, vel;y fri-
able; 30 percent sandstone fragments;
calcareous; neutral; gradual smooth
bomtdary.

(2.5YR 4/4) moist; massive; slightly
hard, very friable; 50 percent sandstone
fragments :uul flagstones; calc:u'euus;
neutral; clear smooth boundary.

The A hm•izon is fine sandy lo:un or light loam 3 Lo
6 inches thick. The C horizon is fine sandy loam, sandy
loran, or light loam. Content of rock fragments, mostly
channery or larger, averages 35 to 70 percent. Reaction
ranges from neutral to moderately alkaline.
82-Pcndcrgraee•Rock outcrop cumplcx, 15 l0 25
perccut slopce. This complex consists of moderately
steep soils on uplands. It is about 50 percent Pender-
grass fine sandy loam and about 35 perccut hock out-
crop. Pendergrass line sandy loam is nem• the Lop of
side slopes and the less sloping areas near the base of
side slopes, attd Rock outcrop is steeper.
Included with this complex in mopping are about 15
percent areas of Miracle and Clergern soils. Also in-
cluded m'e some small areas of soils that :u•e similar to
the Pendergrass soil but in which bedrock is somewhat
deeper and vegetation is mixed cmtifers.
Runoff is rapid, and the haaard of erosion is severe.
This complex is suited to native grasses. Capability
unit VIIs-1, drylmul; Pendergrass soil in Rocky Loam
range site and Rock outcrop not assigned to a range
site; not assigned to a windbreak suitability group.
Plnala SCrtCS
The Pinata series consists of deep, well drained
soils that fm•med in material weathered from sandstone
and shale. These soils are at mountainsides and ridges.
Elevation ranges from 5,800 to G,500 feet. Slopes are
15 to 95 percent. The native vegetation is mainly
ponderosa pine and some juniper and oak brush. Mean
annual precipitation ranges from 15 to 18 inches,
mean annual air temperature ranges ft•om 4G° to 48°
F, and the frost-free season ranges from 120 to 135
days.
In a representative pt•ofile a 1-ittclr-thick layer of
organic material is on the surface. The surface layer
is dark brown stony sandy loam about 2 inches thick.
The subsurface layer is pinkish gray stmty light sandy
loam about 8 inches thick. The subsoil is reddish brown
stony clay about ]2 inches thick and yellowish red
stony clay loam about 20 inches thick. Below this is
hard sandstone.
Permeability is slow, and the available water ca-
pacity is medium. Reaction is neutral.

These soils are used for rect•eation, building sites,
quan'y sites, and limited grazing.

The Al Itor•izott is sandy loam or heavy loamy sand
1 to 4 inches thick. The A2 horizon is light sandy loam
or loamy sand G to 12 inches thick. The B2t horizon is
heavy clay loam or clay. Depth to bedrock ranges from
40 to GO inches or more. Content of rock fragments,
mainly flagstone, ranges from 35 to 80 percent.
