R.E. Johnson 1967 Journal 20 June 10 Mt. Shasta, Siskiyou Co., California (cont.) pass to the east via Mud Creek instead of heading west & south toward the ski lift (either way is easily traversable) because Miller had collected his two rosy finches at the head of Mud Creek at a rather high elevation ( 10,000 ft. ).

I returned up canyon but the bird flew across canyon above the moraine cliffs on that side. I ascended the sw wall which is constantly avalanching & is thus nowhere "safe" to ascend. The wall had been shaded for some
