Acker Rock is a ridge-like formation that towers 3000 feet above the South Umpqua and Buckeye Creek valleys in Oregon's southern Cascades. Acker's summit is home to the historic Acker Rock Lookout, which is still used for fire spotting. Generally it is available for rent from August 1 through November according to the Umpqua Nat'l Forest website.
The Peregrine Traverse is Oregon's longest rock route, comprised of 10 pitches, 5.7 with substantial exposure. Bring driving directions from Mountain Project and an Umpqua Nat Forest map.
