TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, mesic Xeric Haplocambids

TYPICAL PEDON: Minat very cobbly sandy loam, rangeland. (Colors
are for dry soil unless otherwise noted). The soil surface is partially covered with approximately 45 percent pebbles and 25 percent cobbles.

Al--0 to 3 inches; pale brown (l0YR 6/3) very cobbly sandy
loam, brown (l0YR 4/3) moist; weak medium platy structure; soft,
very friable, slightly sticky and slightly plastic; common very
fine and few fine roots; common fine tubular pores; 30 percent pebbles and 20 percent cobbles; moderately alkaline (pH 7.8);
gradual smooth boundary. (3 to 6 inches thick)

A2--3 to 9 inches; pale brown (l0YR 6/3) very gravelly loam, brown (l0YR 4/3) moist; weak medium platy structure; soft, very friable, slightly sticky and slightly plastic; common very fine
and fine, few medium roots; common fine tubular pores; 35 percent pebbles; moderately alkaline (pH 8.0); gradual wavy boundary. (0
to 6 inches thick)

Bw1--9 to l9 inches; pale brown (l0YR 6/3) very gravelly loam, brown (l0YR 4/3) moist; moderate medium subangular blocky
structure; slightly hard, very friable, slightly sticky and
slightly plastic; common very fine, few fine and medium roots;
common fine tubular pores; 50 percent pebbles; moderately alkaline (pH 8.0); gradual wavy boundary. (6 to l2 inches thick)

Bw2--l9 to 27 inches; pale brown (l0YR 6/3) very gravelly
loam, brown (l0YR 4/3) moist; moderate medium subangular blocky structure; slightly hard, friable, sticky and plastic; common very fine, few fine and medium roots; few fine tubular pores; 40
percent pebbles; effervescent in spots; lime coats on undersides
of pebbles; moderately alkaline (pH 8.4); gradual wavy boundary.
(6 to l2 inches thick)

Bqk1--27 to 44 inches; pale brown (l0YR 6/3) very gravelly
loam, brown (l0YR 4/3) moist; weak medium subangular blocky structure; soft, very friable, sticky and plastic; common very
fine, few fine and medium roots; 50 percent pebbles; l5 percent weakly cemented durinodes; lime coats on pebbles; strongly effervescent; strongly alkaline (pH 8.6); gradual wavy boundary.
(7 to l9 inches thick)

Bqk2--44 to 60 inches; very pale brown (l0YR 7/3) very
gravelly fine sandy loam, brown (l0YR 5/3) moist; massive;
slightly hard, very friable, slightly sticky and nonplastic; many very fine roots; 50 percent pebbles; l5 percent weakly cemented durinodes; common medium soft lime masses and coats on pebbles; strongly effervescent; strongly alkaline (pH 8.6)

TYPE LOCATION: Lander County, Nevada; about 32 miles south of
Battle Mountain in an unsectionized area approximately 2,600 feet south and l,500 feet east of the northwest corner of section 6, T. 24 N., R. 42 E.

RANGE IN CHARACTERISTICS:

Soil moisture - Usually dry, moist in winter and spring.

Soil temperature - 47 to 50 degrees F.

Thickness of A and Bw horizons - 20 to 30 inches.

Depth to carbonates - l8 to 27 inches.

Control section - Clay content: 15 to 27 percent.
Rock fragments: 35 to 60 percent, predominantly pebbles,

A horizon - Value: 5 or 6 dry, 3 or 4 moist.
Chroma: 2 or 3.
Reaction: Mildly alkaline or moderately alkaline.
Other features: Some pedons have carbonate recharge in the Al horizon.

Bw horizon - Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 3 or 4.
Reaction: Mildly alkaline or moderately alkaline.

Bqk horizons - Value: 6 or 7 dry, 4 through 6 moist.
Chroma: 3 or 4.
Cementation: 0 to l5 percent weakly cemented durinodes.
Reaction: Moderately alkaline or strongly alkaline.

COMPETING SERIES: These are the Finley, Kiona, Mackey, Veet and
Veta soils. Finley soils have sandy IIC horizons at depths of 20
to 40 inches. Kiona soils have mainly cobbles in the control
section and a mean annual soil temperature of 50 to 54 degrees F. Mackey soils have bedrock between 20 and 40 inches. Veet soils
have a period of appreciable summer moisture for l0 to 20 days in
the summer and sola l2 to 20 inches thick. Veta soils have 5 to
l5 percent clay in the control section and sola l2 to 20 inches
thick and are 28 to 40 inches to carbonates.

GEOGRAPHIC SETTING: Minat soils are on hill and mountain side slopes. Elevations are 4,500 to 6,200 feet. Slopes are l5 to 75 percent. These soils formed in colluvium from chert, shale and
mixed volcanic rocks with some influence from volcanic ash. The climate is cool, semiarid with hot, dry summers and cool, moist winters. The mean annual precipitation is 8 to l0 inches; mean annual temperature is 46 to 48 degrees F., and the frost-free
season is 90 to 110 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Jung and Locane soils. Jung and Locane are shallow to hard bedrock.

DRAINAGE AND PERMEABILITY: Well drained; rapid runoff; moderate permeability.

USE AND VEGETATION: Livestock grazing and wildlife habitat. The vegetation is mainly Wyoming big sagebrush, spiny hopsage, bottlebrush squirreltail, and Sandberg bluegrass.

DISTRIBUTION AND EXTENT: Central Nevada. These soils are of
small extent.

MLRA OFFICE RESPONSIBLE: Reno, Nevada

SERIES ESTABLISHED: Lander County, Nevada, South Part, 1985.

REMARKS: The name is coined.

The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Reno MLRA office, without review of the soil series property data. The remainder of this document has not been updated.

DIAGNOSTIC HORIZONS AND FEATURES IN THIS PEDON ARE:
