Bourman 1952 Journal 13. Aug. 15. 11.5 mi NE Chama, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico: - Although there are a few scattered groves of fir & spruce trees (from 1/2 acre to 5 acres), the greater part is grassy field. There is evidence of greater tree growth here, for in many places there is extensive fall of trees, now grey & weathered. Annual observations as follows: Juncos (black-headed) seen frequently in trees. Shot at a family group 20 ft. off ground in a dead spruce tree. Shot one Chipmunk; aval temp. 15 sec. after shot (dead), 39.80 C. at 8:50 A.M.. Saw 10+ Mt. Bluebirds on the open grassland plateau -- flying from dead stump to stump. Young birds seen fed by adults. Blue Daisies (?) and Crossbills (Red), and 4 Audubon Warblers seen in five trees. Found a small pond (estimated 1 acre in size -- circular) containing hundreds of Necturus (?) ranging in size from 2" to 4", called "mud-dogs" locally. These amphibians were located in the shallow margins of the pond, sunning. Was able to capture only one animal. Water temp. at 10:15 A.H in shade at surface was 61. F. I estimate the pool to be uniformly shallow, probably 3 ft deep at center. Bottom muddy. Could find no frogs or toads in area -- also no kingfishers! About 10 open & spruce trees around edge of pond in 3 scattered cumps. The west-facing slope of this range, at its northerly pt., is rocky covered, ideal for cones, but found none. Ripe raspberries found growing amongst granite boulders. Half way down hillside found a small
