<br />dated with Haxtwi soils in some small areas in the north-
<br />central and northwestern parts of the county. Slopes are
<br />ittoderate to steep, The profile of this soil is similar to the
<br />one described as typical for the series.
<br />Inchtded with this soil in mapping were a few small
<br />blowouts r/a acre to o acres in size. These areas are shown
<br />on the soil map by a symbol.
<br />Wages Series
<br />The Wages series consists of deep, well-drained, loamy
<br />soils that are gently sloping to steep. These soils occupy
<br />the side slopes of intermittent streams (fig, 8), and most
<br />areas are along Frenehmw and patent Creeks. Wages soils
<br />formed in a reddish-brown gravelly deposit. The upper
<br />part of the soil has been mixed with some windblot,-n silty
<br />r material.
<br />Tn a typical profile the surface layer is grayish-brown
<br />loam about b inches thick. The subsoil is about ll inches
<br />thief. In the upper part it is Clark grayish-brortiat, slightly
<br />hard clay loon that is abort ~ percent fine gravel. The
<br />about pro lOs limy, light browfueh-gfuy clay loam that is
<br />percent fine gravel,
<br />.1t a depth of 16 to 24 inches is very strongly calcareous,
<br />light brownish-bray loam. Below this is liglit•btrown
<br />c avelly sandy loam that is free of lime.

<br />layer over a slowly permeable clay loath subsoil and are
<br />geartly sloping to steep, surface runoff is medium to rapid.
<br />Because their subsoil is somewhat gravelly, they have
<br />moderate available water holding capacity. 1Vages soils
<br />are moderate in natln'al fertility,
<br />Tong side slopes of intermittent streams are a few
<br />areas of Wages soils that are still in native grass, mainly
<br />westeri wheats •ass and blue grams. Grasses are better
<br />suited than tiny crops, and only a few aet•es are cultivated,
<br />These soils can he seeded to grass.
