Hatter J.E. 1939 Itinerary Twin Buttes 4200 ft. 2 1/2 mi. SW Steamboat Mtn, Sherman Co. Wash. July 11 (contd) top of a rotten stump at about 10 yards distance - 10:30 A.M. Caught & C. lateralis in rat trap. The country in the vicinity of Twin Buttes has a variety of habitats. The land in the saddle between the buttes where the camp was set up is made up of light sandy loam with some rocks in it. Slopes are gradual and covered with sod in most places; patches of brushy areas are present composed of huckleberry and other low bushes. Tree cover where present consists of white fir, Western Larch and Sugar Pine and a few scattered cottonwoods (?) or poplards(?) Burned areas are present north of the camp about the Ranger Station and Mosquito Lake. These have become covered with fairly heavy brush and many young pines and firs. Farther north heavy timber is found which has neither been logged or burned recently and is very dense. Fallen logs and dense herbaceous growth forms the understory
