Hiking Mt. Thielsen

Continue straight up the hill towards the summit, which is very much in sight at this point. The trail can be hard to follow once you get onto the scree but keep heading up until you hit solid rock.
The final climb to the summit is around Class 4, with mostly Class 3 moves. There are a few different spots here to turn around if you don't want to attempt the final push (including on the ledge known as "Chicken Out Ledge." More than one person has been turned around here.
