PLATE 26 



Fig. 5. The eastern side of the canon at Hompeg Falls, Blue Mountain area. 

 The considerable extent of the rocky-slope habitat at this point is shown. The 

 trees on the slopes are mostly yellow pines (Pinus ponderosa). Toward the 

 upper part of the ridge a yellow-pine habitat occurs. In the bottom of the 

 canon is a lowland-fir habitat. 



Fig. 6. Forests in the Blue Mountains near the head of the South Fork of 

 the Touchet River, Aug. 1, 1915. The forest in this section is chiefly made up 

 of young trees. Douglas spruce (Pseudotsuga taxi folia) and western larch 

 (Larix occidentalis) are the dominant species.
