Cabinet Mtns, Bonner Co., Idaho (cont.)
are rocky, have old snags, and are open grassy with (aster, Castilleja, Lousewort, Lupine) Eriogonum, Yarrow, Alum Root, Penstemon ellipticus being the principle ground cover. The north slopes of these ridges have scrubby low Fir (1-3 ft) + numerous low herbs.
These slopes taper off as talus slopes. There are small snow patches (largest 20 x 80 ft). This habitat isn't much different than Strawberry Mtn, Grant Co., Oregon would be at this date. Strawberry is higher, but farther south, had more snow, but I saw it earlier, and above timberline had a more distinct timberline (top 500 ft of mtn). Here timber has stood on top in the past and still closely approaches the top. The talus and snow are 600 ft or more below the summit making them considerably below general timberline (elevation uncertain however).
There probably is more snow left at Strawberry Mtn than this. It seems very doubtful that Rosy Finch would occur here on Mt. Rend Oseille.
Walking the ridge I encountered a family of Spruce Grouse, Oregon Juniper, Pine Siskins, and Cassin's Finches.
According to the topo map (Mt. Rend Oseille Quad, 15 min. series, 1951, with green overprint) Smith Mtn (8510) has a north facing cirque with a lake (Smith Lake, 5700 ft.) in it & it is untimbered. Perhaps this cirque would have better habitat for Rosy Finches. From here (due east of Mt. Rend Oseille) a small snow patch on the nw ridge can be seen but not the N. face. There is a L.O. on too.
