Camp at Sespe Hot Springs, 12/1986. I have had this labeled incorrectly for a long time. Jon has the correct ID in the comments and the sequence of the negatives from the trip, recovered in August, 2011 confirm this. Note 1980 vintage North Face VE 23 tent. Also note the Jansport D2 frame pack. In the lower right foreground corner is a first generation First Need water filter.
