<br />The A and AC horizons are light sandy toes or
<br />cog rsc loamy sand. The AL horizon is 6 to 20
<br />toches thick and is thinnest in areas that w'e re

<br />Bl::l;eland sandy loam, 1 to 15 percent slopes
<br />(d11.).--7his undulating to rolltna soil occurs on
<br />uplands in the northern part of the Area. 'bst
<br />capped areas arc less than 1G0 acres in s:~c.
<br />Included with this soil in napping a-e wall
<br />ages of 'f ruck ton sandy loan, 3 to B p~.eent slopes,
<br />Lior.rr sandy loam, 3 to 9 percent slopes, and
<br />.`.taple[on loamy sand. Also included arc areas of
<br />Sandy alluvlal land in drainage:+ays.
<br />Sur(aec nmoff is slow to ecdius, depending cn
<br />slope. This soil is subject to sere re soil blowing
<br />if it is tilled or cover is in at!eauate. The ha_a rd
<br />oC•°atcr erosion is slight to mode rate. Gullies

<br />Orsa soils make up about 35 percent of the acreage
<br />and are mostly on foot slopes and in shallow
<br />sw ales.
<br />included with these soils in mapping are small
<br />a rcas of 6resser sandy loam, 1 to 3 percent slopes,
<br />Kasslcr gravel ly sandv Loam, and Sandy alluvial
<br />land. Also included arc small areas of a soil that
<br />is ^~o rc red than, but otherwise similar to, Btake-
<br />land soils.
<br />P.u noff is slow to medium. In cultivated areas
<br />the erosion hazard is slight to moderate and some
<br />gullies have formed. These soils receive runoff
<br />from soils at higher elevation.
<br />host of the ac reagc is in native grass. A few
<br />small areas are used for dryfarmcd grain or irriga-
<br />ted alfalfa. (Capability unit 1\'c-S, dryland; 1Vs-1,

<br />The Bresscr series consists of well-drained soils
<br />that fo rued in sandy soil material deposited by
<br />wind and ~atc r, 'these gently sloping to moderately
<br />steep soils arc on tcrrac es and uplands in the
<br />~•a rncr, no rthc rn part of the Arca. Slopes are 1 to
<br />15 percent. The vegetation is mid and tall grasses.
<br />F,lcvations arc 5,500 to 6,600 feet. Annual precipi-
