Luckily I did bring my flashlight and batteries, otherwise I would have been screwed. I did not plan to stay up so late, but the ascent to the ridge hike took longer than anticipated, and of course, what was a sunny day in the morning progressed to clouds and rainstorm by the afternoon, which continued into the night.
I continued as best as I can. I was acutely aware of the danger of a trip and fall that might break an ankle and hypothermia - some parts of the hike still had snow, and anytime I stopped, I could feel the cold seeping in.
