<br />The Trncclers series t•onsists of sh:dlnw, well
<br />dr;tined or smne+vhat excessively cb;iined soils. 'These
<br />soils formal in rr !doom +vc:rt.hcred from L;is,dt on
<br />foothills ;uui mesas. Slopes are 3 to ?:~ percent. Llera-
<br />tion is 1,500 to 4,500 feet. N:+tural vegetation is domi-
<br />nantly' blue grams, sn;tkeweed, lou• r;lbbithrush, ]ndian
<br />ricegrass, ;old +vintcrfat. The average annual precipi-
<br />tation is about 9 inches, the me;m annlml air tempera-
<br />tw'e is nbuut 91° F, and the frost-free season is 00
<br />to 105 days,
<br />]n a representative profile the surface layer is d;+rk
<br />brown very stony loam about 3 inches thick. The sub-
<br />soil is dark bro+yn very stony' loam about 0 inches
<br />thick. The substratum is grayish brot+n loam about
<br />7 inches thick. Easalt is at a depth of about ]G inches.
<br />Permenbilit•Y is moderate, :uxi the available wafer
<br />capacity is ]o+y. F.c,+rtion is moderately alkaline. The
<br />effective rooting depth is 10 to 20 inches.
<br />These soils are used for range, wildlife, and recrea-
<br />tion.

<br />The Al horizon is 2 to u` inches !hick and is very stony

<br />inches thick and is loam or light clay loam. The content of
<br />coarse fragments, dominantly basalt stones and cohbles,
<br />range from 25 to 75 percent in the R and C horizons. Depth
<br />Lo bedrock ranges from ]0 to 20 inches. RFdrvrck is drnni-

<br />soil occupies foothills and small mesas along the west-
<br />ern edge of the valley. The profile of this soil is similar
<br />to the one described as representative of the series,
<br />but the surface laver is very stony sonde loam. About
<br />15 percent of this unit is included :u'eas of Carita
<br />cobbly loam, ~ to 35 percent slopes, and about ]0 per-
<br />cent :u'eas of Pock outcrop.
<br />Runoff is moderate. The hazard of +vater erosion is

<br />Runoff is moderate to rapid. 'rho hazard of water
<br />erosion is moderate. Small gullies have fm'med on
<br />many of the sleeker slolres. A1ost of the small valleys
<br />are cut b> ;gullies 2 to 8 feet deep and 3 to ]0 feet ++'ide.
<br />This mapping unit is used for range :md +vildlife.

<br />m• pom•lp drained and occupy ]ow, nearly level flood
<br />plains along the F.io Grande and some of its majw• '
<br />tributaries. Slopes are 0 to 1 percent. Fluvaquents
<br />formed in alluvium more than 20 inches thick over
<br />sand and gravel The surface layer and underlying
<br />layer range from Inam to clay loam. In marry places
<br />the soil material is highly' stratified. There are many
<br />old stream channels and osbo++'s.
<br />Salinity is low to moderate. The water table is at a
<br />depth of ]2 to 29 inches late in spring and in sunnuer,
<br />but drops to 30 to 60 inches in winter. Flooding is a
<br />hazard in spring ++'hen runoff is high frmn melting
<br />snu++• in the mountains. Permeability is moderate to
<br />moderately slo++', and available ++'ater capacity is mod-
<br />erate. Runoff is slow. The erosion hazard is slight.
<br />Topic Flucaquents are used fm- irrigated meadow,
<br />irrigated small grain and alfalfa, and for range. 1\'fead-
<br />o+rs are cuf fm• hay or used for grving. Vegetables
<br />:end potatoes are not suited, \atural vegetation is alkali
<br />sacaton, sedges, rushes, and +vestern tvheaigr;,ss.
<br />Capability unit lll+y-2 irrigated, \']w-1 nonirrigated;
<br />Salt :lleado++' range site.
<br />Typic Torriflmrn[s
<br />Tu-T+pic Turri(lu+rnls are nearly level and exces-
<br />sively drained and occupy the flood- plain of the Rio
<br />Grande. Slopes are 0 to 1 percent. The soils range from
<br />Inam to sandy loam and are generally' stratified and
<br />underlain by' sand and gravel at a depth of 4 to 20
<br />inches, On about 20 percent of this unit the soil mate-
<br />rial is doel,er over sand and gravel because old stream
<br />channels have been filled in. ]ncluded in mapping are
<br />gravel bars, +vhich make up about ]0 percent of the
<br />unit.
<br />Typic Tm'rifiucents are droughty. Permeability is
<br />moderately rapid. and the available water capacity- is
<br />lo+y. 'fhe ++'ater table is generally more than 3 feet deep,
<br />but rises to ? to 3 feet fa- short periods late in spring
<br />and early' in summer ++97en runoff is high from melting
<br />sno+v in the mountains. Runoff is slow. The erosion
<br />hazard is slight,
<br />Typic Ton•iHucents are used mainly for t.ange. Some
<br />areas are used for wildlife. Some small areas are used
<br />for irrigated small grain and alfalfa. \atur'al vegeta-
<br />tion is cottonwood and +villows and an understory of
<br />morasses and sedges. Capability' unit 1Vs-9 irrigated,
<br />VIIvti•-1 nonirrigated; not assigned to a range site.
