Huerfano County Area, Colorado

The surface layer is moderately coarse textured, Below
this, to a depth of 60 inches or more, the soils are
medium textured or moderately fine textured,
Bayerton soils are on mountainsides and foot slopes,
These soils are moderately deep and well drained. They
formed in residuum derived dominantly from sandstone,
The surface is covered with a mat of pine needles and
leaves. The surface layer is moderately coarse textured
and has some rock fragments. The subsoil is medium
textured or moderately fine textured. Unweathered
sandstone is at a depth of 25 inches.
Ring soils are on terraces. These soils are deep and
well drained. They formed in alluvium derived dominantly
from mixed sediment. The surface is covered with a mat
of pine litter. The subsoil is moderately coarse textured
and has some rock fragments. Below this. to a depth of
60 inches or more, the soils are fine textured and have
many rock fragments.
Of minor extent in this unit are Wahatoya, Noden,
Badito, and Breece soils. The Wahatoya and Badito soils
are moderately deep and have many rock fragments.
The Noden and Breece soils are deep and are in
drainageways.
This unit is used as woodland and for livestock grazing
and wildlife habitat.
Wildlife such as mule deer, elk, turkey, cottontail,
coyote, bobcat, porcupine, squirrel, and limited numbers
of band-tailed pigeon inhabit this unit.
If this unit is used for homesite development, the main
limitation in most areas is steepness of slope. In the less
sloping areas of the unit, moderate shrink-swell potential
is the main limitation.

14. Goemmer-Fughes

Moderately deep and deep. well drained, gently sloping
to very steep soils; on mountainsides, foot slopes, and
benches

This map unit is in the south-central, southwestern,
and western parts of the survey area. Slope is 3 to 50
percent. The vegetation is mainly grass on the gently
sloping soils and ponderosa pine and oakbrush on the
steeper soils. Elevation is 7,300 to 8,500 feet. The
average annual precipitation is about 18 to 25 inches,
the average annual air temperature is 40 to 44 degrees
F. and the average frost-free season is 70 to 100 days.
This unit makes up about 2 percent of the survey area.
It is about 55 percent Goemmer soils and 10 percent
Fughes soils. The remaining 35 percent is components
of minor extent.
Goemmer soils are on mountainsides. These soils are
moderately deep and well drained. They formed in
colluvium and residuum derived dominantly from shale
and siltstone. The soils are fine textured throughout.
Some rock fragments are in the surface layer.
Fughes soils are on foot slopes and benches. These
soils are deep and well drained. They formed in
colluvium derived dominantly from shale and siltstone.

The surface layer is moderately fine textured. The
subsoil is fine textured. Below this, to a depth of 60
inches or more, the soils are moderately fine textured.
Of minor extent in this unit are Holderness, Ring,
Tolman, and Castner soils. The Holderness soils have
bedrock at a depth of 50 inches. The Ring soils are deep
and have many rock fragments. The Tolman and
Castner soils are shallow over bedrock.
Most areas of this unit are used as rangeland and for
wildlife habitat. A few of the more gently sloping areas
are used for irrigated hay and pasture.
Wildlife such as elk, mule deer, turkey, cottontail,
grouse, and limited numbers of black bear and mountain
lion inhabit the unit. Areas used as cropland provide
additional food and cover.
This unit is poorly suited to homesite development.
The main limitations are high shrink-swell potential and
steepness of slope.

15. Leadville-Lakehelen-Uinta

Moderately deep and deep, well drained, gently sloping
to extremely steep soils; on mountains and benches

This map unit is in the western and southwestern parts
of the survey area. It is mainly on mountainsides, but it is
also on mountaintops and benches. Slope is 4 to 80
percent. The vegetation on this unit is mainly conifers.
Elevation is 8,000 to 10,000 feet. The average annual
precipitation is about 20 to 30 inches, the average
annual air temperature is 38 to 45 degrees F, and the
average frost-free season is 40 to 70 days.
This unit makes up about 5 percent of the survey area.
It is about 25 percent Leadville soils, 20 percent
Lakehelen soils, and 10 percent Uinta soils. The
remaining 45 percent is components of minor extent.
Leadville soils are on mountainsides. These soils are
deep and well drained. They formed in colluvium and
residuum derived dominantly from sandstone. The
surface is covered with a mat of needles and twigs. The
surface layer is moderately coarse textured. The subsoil
is moderately fine textured and has many large rock
fragments. Below this, to a depth of 60 inches or more,
the soils are moderately coarse textured and have many
large rock fragments.
Lakehelen soils are on mountains. These soils are
moderately deep and well drained. They formed in
residuum and colluvium derived dominantly from
sandstone. The surface is covered with a mat of needles
and twigs. The surface layer is moderately coarse
textured. The subsoil is moderately fine textured and has
many rock fragments. Unweathered sandstone is at a
depth of 28 inches.
Uinta soils are on mountainsides and benches. These
soils are deep and well drained. They formed in
residuum and colluvium derived dominantly from
sandstone. The surface is covered with a mat of forest
litter. The surface layer is moderately coarse textured.
Below this, to a depth of 60 inches or more, the soils are
moderately fine textured.
