R.E. Johnson 1966 34 Journal West Fork Yaak River, 5000 Ft., Lincoln Co., Montana (cont.) June 27 A higher side cirque is soon reached extending at right angles to the main canyon (to the north). The floor of this higher valley is flat and broad and subalpine in nature. Engleman Spruce, Alpine Fir, & Snags are scattered through the area (also Alpine Larch). Ground cover includes Glacier Lily, Beargrass, Globeflower, & Sedge. Patches of snow cover 10% of the area. A Hairy Woodpecker was collected from a snag. Clark's Nutcracker, Hermit Thrush, White-crowned Sparrow, and Pine Siskins were seen. Coyote & Hoary Marmots were heard in the rock slides on the west side of the cirque. This side was ascended in pursuit of a pair of Townsend Solitaires which I failed to collect. Mtn. Bluebirds were also seen. Upon reaching the ridgetop above the cirque, I went north along the ridge toward the head of the cirque & Mt. Ewing (7536 Ft.) [referred to on labels as "Pk west of Davis Mtn"]. The ridgetop is rocky with occasional patches of turf. Boulder slides extend down the east slope into the cirque. Formed soil extends up the west slope & ofen is forested with Spruce & Fir. Snow overhangs much of the east slope in cornices, but the ridgetop itself is generally free of snow. The turf patches include: Glacier Lily (Erythronium grandiflorum), White Heather (both Phyllodoce glanduliflora & Cassiope mertensiana), & Spring Beauty (Claytonia lanceolata). The remains of winter Microtus runways were seen in several places.
