The atmosphere is cool and gray, and the first layers of high-elevation snow have cast a renewed sense of dimension and personality upon the massive peaks above, their tips immersed in soft November clouds. I walk on tribal lands in the Mission Mountains, and cut off trail to saunter along the stream.
