Bowman 1952 Journal 12. Aug 14 11.5 mi. NE Choma, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico - yesterday which showed a light colored dorsal tail surface, while the other was light-colored. The following bird temperatures were recorded: Species Temp. Time Condition Black-headed Junco 39.2° C. 8:03 A.M. dead 15 sec. Mt. Bluebird 38.9° C 9:10 A.M. dying Mt. Bluebird 40.0 °C. 10:20 A.M. alive (broken wing) Found the fore-leg of a snowshoe hare (winter pelage) and 25 ft distant, a tail feather from a Red-tailed hawk. At 5:45 P.M. set out 35 Museum Specimens south of camp in wooded marshy area. Aug 15. Pick-up of Museum specimens at 5:50 A.M.- Only one Zapus taken in meadow beside a log. Temp. at 5:45 A.M. at camp, in shade 42° F. Frost on ground. From 7:00 A.M. to 11:00 A.M. hiked the mountain range east of camp. The shaded W-facing slope is heavily wooded & damp. Found liverwort growing profusely on ground. Found golden-mantled ground squirrels digging on a rocky- ground covered plateau. Good view of the Sangre de Cristo range to the east. --- appears like a saw-tooth range, considerably higher than any of the surrounding country to the N, S, or W. This mountainous country is surprisingly flat & tame, reminding me much of the topography in central British Columbia in the N. part of Tweedsmuir Provincial Park. The plateau east of camp is approx. 1000 ft. higher than our camp, thus making it 11,000 ft.
