35 rises seems to serve as a stanch barrier at this point. In the late afternoon Bill took forward & I nearly all the way to summit of Mt. Harrison & left us there to return for us in 4 days. He would visit relatives in Rupert. The life zones on the Mt. are very mixed up. Vegetation on the N.E. slope was entirely sage until about 6000' when there occurred a few small Aspens beside streams extending in toungues down the slope. Their leaves were out but small as yet. Sage (Asteromia tridactyla) occured on some of the drier ridges & would be seen all the way up the summit. Perhaps the reason for this shrub occuring in such varied habitat (dust to snow peak) is due to its relation to water supply & not temperature. Either is broadly tolerant to conditions or because it really can't get any more water on the snow peak due to its being in an icy form & not obtainable - thus can get same amt. of water in desert as the peak. On climbing, the first conifer met with was the Douglas Fir. Then came Red Firs (then a mixture of Lodgepole Pine & firs) to the top. Yellow-Haired Porcupine - On Mt. Harrison
