Tanner Butte, OR | August 2016
Tanner Butte is perhaps the most remote SOTA summit in Oregon's Northern Cascades. Despite many resources that point out the trail length at 17 miles, measured from the GPS track it shows up as right at 20 miles round trip, with 4500 feet of elevation gain. You won't see many other hikers on these remote trails. NOTE that this area burned in the Eagle Creek Fire in 2017 and trail conditions have likely substantially changed.
