Bournon 1952. Journal 43. Sept.6. 6 mi. E Truchas, 10,000 ft., Rio Arriba Co., New Mexico succession here. The photograph includes only a portion of the situation depicted in cross-section in the following sketch. S ASPEM (58') D.FIR SPRUCE (6') GROUd JUNIPER (2-3') SOil gravelly (granite base) Hill Douglas FIR (65') Douglas FIR (10'-15') ground level Humus soil. See photo 3/6 covering this section only Observed a cache of a Chickaree (?) below a Douglas Fir tree. Small holes were dug in the needle layer, + fresh cones buried in these. The poplar appears to be a recovery stage from burning in at least one large area studied. Charred logs are everywhere apparent, + dead logs, almost completely decayed. From what I can view from the sole vantage point here, at least 40% of the mountain slopes nearly are aspen covered. At dusk, saw numerous bats flying overhead. There seemed to be at least 2 sizes present. Stuart Hendry shot one Myotis sp. Saw a group of 4 Nighthawks + 2 Ravens flying NE, against a very heavy E wind. S.O.
