. Contour trenching effects on streamflow from a Utah watershed. Watershed management Utah; Drainage. Some important geologic features may influence the results of this study. With the use of a detailed geologic map (Bell 1952), a comparison of fault lines with stream locations and strike and dip information with contour lines explains the occurrence of the contact zone in the Halfway Creek drainage. Prevailing winds move considerable snow out of the Halfway Creek drainage. Springs, fed by the large accumulation of snow in the cirque basin immediately to the east and from seepage along the fault zone, return some of this moisture to the Halfway Creek drainage. Soils are generally coarse textured, immature, rocky, and shallow. Parent mate- rial was disintegrated in place by frost action and the resulting surface material in the trenched area is approximately 7 feet thick. Vegetation Halfway Creek drainage may be divided into five major vegetation zones (fig. 4). Aspen {Populus tremuloides) occupies the wetter sites along stable stream courses just below the contact zone. Adjacent to the aspen, on slightly drier sites, are the ceanothus {Ceanothus velutinus) and mixed browse (Amelanohier utahensis, Prunus virgin- â uzruXj Symphoriaarpos sp., Alnus tenuifolia) zones. The ceanothus and mixed browse zones form dense thickets of brush with little understory. The two are separated because ceanothus completely dominates sites on which it occurs and forms a much shorter type of cover. Along the upper ridges and drier midslopes, two species of sagebrush (Artemisia tvidentata^ and Artemisia soopulorum) predominate. A variety of grasses and forbs form the ground cover.
