MP 2601   I crossed a highway and headed up as it started to get dark.    The trail switchbacked up a mountainside with a steep grade, maybe 100 degrees  (45 degree angle).   Finally found a small niche in a hollow next to a large, old-growth fir tree.   No room for the tent here.    Unfortunately it did start raining, lightly, during the night.    I pulled my tent over myself like a sheet and fell back to sleep.
