22 SOIL SURV&Y The hazards of water erosion and soil blolving are sever in cultivated areas. Gullies form in drainageways in son: places. Included in mapping are small areas of san and gravel deposits and a few small areas of Ascalo soils. Most areas of this soil are cultivated, but some area have a cover of native grass. Capability unit VIe-1, nor irrigated; Loamy Plains range site; tree planting sui~ ability group L Tassel Series Stoneham loam, 0 to 3 percent slopes ISrel.-This soil is in scattered areas along major stream channels ill the county. It is on uplands back from the stream channels. The areas are irregular in shape and range from 30 to 50 acres in size. This soil has a profile similar to the one described as representative for the series, but it has a thicker surface layer and subsoil. Runoff is medium to slow. Water erosion and soil blowing are moderate hazards. Included in mapping are a few small at;eas of Platner loam that commonly are in small depressional areas. Most areas of this soil are cultivated, but a few areas remain in native grass. Capability unit IVe-3, nonirrigated; Loamy Plains range site; tree planting suitability group 1. Stoneham loam, 3 to 9 percent slopes ISrD).-This soil has the profile described as representative for the series. It is on uplands near major stream channels in scattered areas throughout the county. The areas are uniform in shape and range from 50 to 80 acres in size. Runoff is generally medium but is rapid it the soil is unprotected. The Tassel series consists of well-drained to somewha excessively drained, gently sloping to strongly slopiu soils on uplands. These soils formed in loamy materil underlain by sandstone at a depth of 10 to 20 inches. Iii a representative profile, the surface layer is brow and pale-brown fine sandy loam about 5 inches thicl It is calcareous- The underlying material is very pal brown and light yellowish-brown fine sandy loam. It '. highly calcareous. Sandstone bedrock is at a depth c 18 inches. Sandstone fragments are generally throughou Tassel soils absorb water ra~lidly, and the availabl water capacity is low. Permeability is moderately rapit and the entire soil is suitable for roots. Representative profile of a Tassel fine sandy loaf having a slope of 6 percent, in an area of grass, 2,60 feet east and 1,300 feet south of the northwest corne of section 4, T. 3 S., R. 58 W.: All-0 to 2 inches, brawn (lOYR 5/3) fine sandy loam, dar brown (lOYR 4/3) when moist; very weak, thin, plat structure; soft, friable; calcareous; mildly alkaline clear, smooth boundary.

R-18 inches, partially weathered, soft sandstone beds; var able in color, texture, and hardness. The A horizon ranges from 2 to 7 inches in thickness, frm pale brown to grayish brown in color, and from fine sand loam to loamy fine sand in texture. The C horizon range from 7 to 1S inches in thickness over sandstone and fr0i very pale brown to light yellowish brown and pale yello~ in color. 'Depth to bedrock ranges from~l0 to 20 inches. Terrace IJscarpments Terrace escarpments lTcl occur as breaks or stee) side slopes adjacent to the channels of present or focme streams. They also occur as the steep faces of terrace that border bottom lands and ftuod plains. This land type consists of alluvium of variable material and is very shallow over gravel and sand. These material -have a loamy sand or sandy loam surface layer. In main areas this layer is 5 to 20 percent gravel. Shale and sand stone outcrops are in some areas. Included in mapping an very small arcas of a Vona loamy sand, a Vona sandy loam and a Dacono loam, all good soils for farming. Figure /1. Profile of a Stoneham loam.
