TYPE LOCATION: McKinley County, New Mexico; Shoemaker Canyon Quadrangle; about 3 miles east of state highway 32 and .75 miles north of the Cibola county line; 34 degrees 58 minutes 13 seconds north latitude, 108 degrees 34 minutes 58 seconds west longitude.
RANGE IN CHARACTERISTICS:
Soil Moisture - Intermittently moist in some part of the soil moisture control section December through April and July through October. These soils are saturated for about one month in the lower part of the Bt horizon in the early spring due to snowmelt. The period of maximum precipitation is July through October. The soil is driest during May and June. Typic Ustic soil moisture regime.
Soil Temperature: 42 to 47 degrees F.
Depth to bedrock: 20 to 40 inches
Reaction: Medium acid to neutral
A horizon -
Hue: 7.5YR or 10YR
Rock fragments: 0 to 10 percent gravel
0 to 5 percent cobbles
Bt horizon -
Hue: 5YR or 7.5YR
Mottles: few to common, fine to medium, faint to distinct, in shades of brown, yellow and red.
Texture: sandy clay loam or fine sandy loam, but averages 20 to 35 percent clay on a weighted average. Rock fragments: 0 to 10 percent gravel
0 to 5 percent cobbles
COMPETING SERIES: These are the Alderon (WY), Allens Park (CO), Bayerton (WY), Belltower (MT), Elbeth (CO), Elbuck (NM), Elmark (MT), Haugan (MT), Heflin (CO), Hoyt (MT), Jemco (CO), Jemez (NM), Kunz (UT), Kwiavu (CO), Littlepine (CO), Losindios (NM), Lumpgulch (MT), Northrim (CO), Plome (CO), Rule (CO), Sweetweed (MT), and Tunitcha (NM) series. Allens Park soils have hues as yellow as 2.5Y and are moderately deep to granite. Alderon, Elmark, Lumpgulch soils are moderately deep to a paralithic contact. Belltower, Elbeth, Elbuck, Haugan, Heflin, Hoyt, Kunz, Kwiavu, Littlepine, Losindios, Northrim, Plome, Rule, and Sweetweed soils are very deep. Bayerton and Jemco soils are well drained and do not have redox features. Jemez soils are moderately deep to tuff. Tunitcha soils are deep to shale.
GEOGRAPHIC SETTING: The Shoemaker soils are on summits of plateaus, mesas, and hills, and dipslopes of cuestas. Slopes are 2 to 8 percent. They occur at elevations of 7,000 to 7,600 feet. These soils formed in reworked alluvium, slope alluvium and eolian material derived from sandstone and shale. The mean annual temperature is about 40 to 45 degrees F. The mean annual precipitation ranges from about 16 to 20 inches. The frost free period is about 90 to 110 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Stout, Valnor and Techado soils on hills, plateaus and ridges, Trag soils on mesas and plateaus and Millpaw soils on terraces and valleys. Stout soils are shallow to sandstone and lack an argillic horizon. Valnor soils are fine textured and less than 40 inches to a paralithic contact. Techado soils lack an argillic horizon and are shallow to shale. Trag and Millpaw soils have a mollic epipedon and are deep.
DRAINAGE AND PERMEABILITY: Moderately well drained; low to high runoff; moderate permeability.
USE AND VEGETATION: These soils are used for woodland and wildlife habitat. Present vegetation is ponderosa pine, pinyon pine, juniper, oak, mountain muhly, pine dropseed, bottlebrush squirreltail, and junegrass.
DISTRIBUTION AND EXTENT: West Central New Mexico. MLRA 35, LRR-D. This series is of small extent.
