This photo was taken on the trail leading up to the western approach of Black Rock Pass. The trail notes are a bit sketchy, It's about 2 hours from Big Arroyo to Little Five Lakes, then it's 2 miles from there to the top of the pass. However, the notes describe them as "extended industrial strength Sierra miles." The view from the top is rather cool, especially towards the west; one can see Mt. Whitney from that vantage point.
