Yup. Found the mine shaft. Neato!
Let me clarify Gimpilator's Summit Log statement: We headed east along the trail, and then continued east off-trail and up the western slopes of the mountain. Once we were at the ridgetop, we stayed on the east side of the ridgetop to reach the true summit. With a good amount of elevation gain in a short distance, as well as some bouldering and scrambling, this was a great way to end our summiting trip in Okanogan County.
This was part of a 3 day, 60 miles of hiking trip that Redwic and I made by driving around different parts of Okanogan County. I broke my arm back in July so I could only use one trekking pole. Clark is worth doing if you are in the area. We came directly up the southwest side and were surprised by the short scramble sections at the end.
