Went from Grey Copper up the OHV road as far as I could. Unfortunately, this only gets you to roughly 12,200 feet. The rest is all route finding to the ridge. I would estimate the ascent is 30% medium scree, 30% dirt road, 30% plants. There are very few cairns and some deer trails. For me, it was easiest to hit the middle 13er in the ridge, then went over to Brown from there. I couldn't stand the thought of retracing my tracks so decided to descend directly down the ridge back to Grey Copper. Ascent was 5.75 miles 3800 feet of elevation. Entire loop was 10 miles, 3800 elevation.
