The fifth, or oakbrush {Quercus gambelii) zone, occupies more than 50 percent of the drainage. This zone ranges from sparsely veg- etated dry slopes where mountain mahogany {Ceroooarpus ledifolius) also is common to wetter sites, areas covered with dense oakbrush intermixed with maple {Aoer glab rim). The Miller Creek drainage tends more toward forest and is generally much more densely vegetated than Halfway Creek drainage (fig. 5). Here, subalpine fir [Abies lasiooarpa) occupies much of the upper middle part of the drainage, the ceanothus zone on the Halfway Creek drainage. Fir is interspersed with clones of quaking aspen. Because of the exposure and the wetter site, aspen is also found well down into the bottom of the drainage in the mixed browse zone. Sagebrush grows along the tops of both drainages. An additional zone, the grass-forb, occurs on those areas where snowbanks persist late into the summer. 6.
