). The Petrified Forest Trail is a one-mile (1.6 km) loop, winding up the side of a mesa to the top where most of the fossil wood occurs. Logs two feet or more in diameter are seen at several places along the trail where it is eroding from the conglomerate capping the mesa. This conglomerate lies near the top of the Brushy Basin Member of the Morrison Formation.Morgan, S., B.W. Lindsay and A.P. Williams 2010. Geology of Escalante State Park, Utah.
