The Rock Corral on the Barlow Road is a glacial erratic, on Oregon's Barlow Road, itself a new route on the Oregon Trail.
Its location
It is on the way to Marmot, where the Barlow Road then goes southwest cross the Devil's Backbone and back across the Sandy River.
It is in Clackamas County, and was at the end of the Oregon Trail's most difficult, most dangerous passage over the Cascade Mountains. The Barlow Tollgate was once there.
