Journal R.E. Johnson 1966 West Fork Yaak River, 5000 ft, Lincoln Co, Montana (cont.) July 7 willow areas & Timber Hermit Thrushes & Wilson's Warblers sang. Higher on the ridge Townsend Solitaries were very common. Chipping Sparrows, Clark Nutcrackers, Mtn. Bluebirds, Pine Siskins, a Rock Wren, Red-shafted Flicker, Audubon Warblers, a Robin, and Oregon Juncos were seen along the ridge at various points. A White-crowned Sparrow & Clarkes Nutcracker were collected. The ridge top is barren & rocky on its eastern end. Higher (west) it has snow patches, stunted trees, a patch of dead snags, and finally scrubby trees leading to (& on) the summit of Davis Mtn. The south slope of the ridge is dry, rocky, & fairly open (low bushes, many dead snags); the north slope has large snow patches, a few narrow meadow ledges (some dry, some wet), and some open forests. Trees are mostly White-barked Pine, Alpine Larch, & Engelmann Spruce. Turf vegetation includes Glacier Lily, Juncus, Heathers, & Huckleberry (dwarf). The top of Davis Mtn is covered with stunted trees. The large cirque on its NW slope (mentioned in yesterdays notes) does not appear to have any rosy finches. The cliffs a the highest I've seen in this area. There is less snow than I had expected at the bottom (still a considerable amount) perhaps because of the low elevation of the base.
