Abstract

Southeast South Dakota has a macro-climate environment favorable to grass. It is a natural prairie area where moisture generally is limiting for trees unless natural landscape conditions shift the microclimate in a cool-moist directions. The Newton Hills area provides these special conditions. A dissected plateau with local relief measured in hundreds of feet slopes steeply in a northeasterly direction to the trench of the Big Sioux River. This northeast-facing slope escapes the direct rays of the sun and an environment more cool and moist than the adjacent prairie upland is formed. Relict trees have persisted in these areas and under the trees there has developed a soil having characteristics which intergrade between wooded and grassland soils. It is the purpose of this thesis to investigate the field and laboratory characteristics of this intergrade soil and to discuss its genesis.
