MP 1844 Hiked across the rim of Crater Lake. Smoke from forest fires was so thick that times we could not see the other side of the lake. Have been hiking with Hamburger. He and I apparently look so old and trail worn that we have been frequently stopped by tourists who want to take our picture. Camped at water cache below the rim. About 2 or 3 in the morning it started to rain and I was gratified to learn that I could set up my tarp in the dark. Woke up with the rain drumming on my tarp which provided the perfect excuse to sleep late.
