BRYMAN SERIES
The Bryman series consists of deep, well drained soils that formed in alluvium from dominantly granitic sources. Bryman soils are on terraces and older alluvial fans and have slopes of 0 to 15 percent. The mean annual precipitation is about 4 inches and the mean annual temperature is about 63 degrees F.

TYPE LOCATION: San Bernardino County, California; approximately 2 miles west of Adobe Corners; 100 yards north of the intersection of Palmdale Road and Duncan Road; SW1/4 SE1/4 SE1/4, section 16, T.4N., R.1E.
RANGE IN CHARACTERISTICS: Solum thickness is more than 30 inches. Depth to carbonates is usually about 30 inches, and ranges from 24 to 32 inches, but the series lacks a calcic horizon. The mean annual soil temperature at a depth of about 20 inches is about 65 degrees F., and the soil temperature usually is not below 47 degrees F. at any time. The soil is usually dry and is not continuously moist for as long as 60 days.
The A horizon is usually pale brown, light yellowish brown or very pale brown (10YR 6/3, 6/4, 5/4, 7/3, 7/4). In some pedons, it is pink or pinkish gray (7.5YR 7/4, 7/2). It is loamy sand, loamy fine sand, or stony sand and averages 3 to 8 percent clay. It is sandy clay loam in overwash areas and averages 20 to 23 percent clay. Structure ranges from moderate fine to thick platy, but is weak or moderate, very fine to medium subangular blocky in some pedons or is massive. Typically this horizon is noncalcareous and mildly alkaline or moderately alkaline, but some pedons are neutral or slightly calcareous in the upper few inches. The surface has been largely reworked by wind action and thickness ranges from 6 to 18 inches.
The B2t horizon is reddish brown or reddish yellow (5YR 5/4, 5/3, 4/4, 6/6, 6/8). It is typically sandy clay loam or clay loam and averages 20 to 35 percent clay. A few pedons are gravelly sandy clay loam with coarse fragments that range up to 30 percent by volume. This horizon typically has strong or moderate coarse prismatic structure. A few pedons have moderate or strong, fine to coarse, angular or subangular blocky structure. This horizon is mildly alkaline or moderately alkaline.
The B31tca horizon is usually pink, or strong brown (7.5YR 7/4, 5/6, 5/8); or less commonly very pale brown (10YR 7/3, 7/4). It is sandy loam, loam or gravelly sandy loam. Some pedons are massive. This horizon is slightly calcareous to strongly calcareous. Segregated lime ranges from few to common, fine to medium, seams, threads, or soft masses, but do not qualify for a calcic horizon. Fine gravel usually ranges from 0 to 5 percent but some pedons have individual strata with up to 20 percent.
The B3 horizon is light brown, reddish yellow (7.5YR 6/4, 6/6, 6/8) or light yellowish brown (10YR 6/4). It has 0 to 5 percent fine gravel. Thin clay bridges between mineral grains are absent in some pedons.
The C horizon is light yellowish brown, very pale brown (10YR 6/4, 7/3, 7/4) or strong brown (7.5YR 5/6, 5/8). It ranges from loamy coarse sand to sand. This horizon is generally moderately alkaline but is strongly alkaline (pH 8.5 to 8.6) in some pedons and has some segregated lime seams or threads. Fine gravel usually ranges from 5 to 10 percent but some pedons have individual strata with up to 20 percent.

Chimenea soils are underlain by highly weathered granite at 6 to 20 inches. Hi Vista soils have a lithic contact at a depth of less than 40 inches. Neuralia soils have hue of 7.5YR or 10YR in the argillic horizon and lack prismatic structure. Dona Ana and Tres Hermanos soils are calcareous throughout, have a calcic horizon at a depth of 20 to 36 inches and have sola 12 to 35 inches thick. Garlock soils are noneffervescent to a depth of at least 40 inches and have hue of 7.5YR or 10YR in the argillic horizon. Milham soils have hue of 10YR in the argillic horizon. Palomas soils are deeper than 36 inches to carbonates. Tijeras soils have sola 10 to 24 inches thick and lack prismatic structure in the B2t horizon.
GEOGRAPHIC SETTING: Bryman soils are on terraces and older alluvial fans and have gradients of 0 to 15 percent. They formed in mixed alluvium derived mainly from granitic sources. Elevations are 2,800 to 3,800 feet. The climate is arid with hot, dry summers and cool somewhat moist winters. The mean annual precipitation is 4 to 6 inches with most of the moisture occurring as rain in late autumn and winter. Some moisture falls occasionally as snow. The mean annual temperature is 61 to 65 degrees F.; the average July temperature is about 44 degrees F.; and the average July temperature is about 83 degrees F. The frost free season is 190 to 255 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are
Helendale,
Cajon and
Rosamond soils. Helendale soils have a coarse, loamy particle size control section. Cajon and Rosamond soils lack an argillic horizon.
DRAINAGE AND PERMEABILITY: Well drained; slow runoff; moderately slow permeability. Some areas are subject to flooding for 1 to 2 weeks from December to early February.
USE AND VEGETATION: Use for irrigated crops such as alfalfa, small grains and pasture. They are also used for homesites and recreation. Vegetation is mostly creosotebush, bursage, Morman-tea, Joshua tree, and annual forbs and grasses.
DISTRIBUTION AND EXTENT: Terraces and older alluvial fans of the Mojave Desert of California, in MLRA 30. The soils are moderately extensive.
