10.4 Remote Sensing and Ecosystem Management Examples
MAP UNIT: 3322
Mountain big sagebrush I Slender wheatgrass (ARTV2IELTR7, Amesmont Family - ARCA V,
Cambern Family ET - ARTV2IELTR7, Guiser Family ET Complex)
This map unit consists of lateral and recessional glacial moraines with intermorainal swales, potholes,
and kettles on moderately sloping undulating till plain. The ARTV2/ELTR7, Amesmont Family ET
occurs on dry moraine sideslopes, till plains, and dry swales. The ARCA V2, Cambern Family ET
occurs on moist positions including swales. The ARTRV2/ELTR7, Guiser Family ET occurs on dry
moraine crests and backslopes.
