Bowman 1952 Journal. 39. Sept.4 6 mi. E. Truchas, 10,000 ft., Rio Arriba Co., New Mexico In the small valley immediately below camp there is a field of wheat. Some vegetables, radish & turnip are also cultivated. On the flat above camp there is a field of oats + a legume, & a field of potatoes. So far we have seen no sign of humans. At sundown (6:25 o'clock) we began seeing bats (presumably Myotis - one taken on Sept.3). They are fast fliers, frequently flying in a straight line. They are 'flocking' over an open valley area W of camp and over the stream to the south of camp, where alders & firs have been recently felled. Dr. O.P. Pearson shot 3, retrieved 2. The temperature is falling rapidly at this writing. The cold air forms a steady stream as it pours down the valley in which we are camped. Frost was detected on the ground this morning. Some of the aspens show a slight lightening in color. One one of the aspen covered slopes, observed a vigorous young growth of 10-15 ft. firs coming in under the aspen. Many of the aspen measure 20" across at their bases. Douglas Fir are about 1 1/2 feet across, although many of those cut in the area are rotten at the core. This are resembles the 11.5 miles NE of Choma composite, in that all the vegetation is lush. The undercover is much denser here, however and all the trees seem to be of larger stature. Some daisy, paintbrush, & clover are in bloom in the more shaded areas.
