Upper Canyon Trail A Professional Review and Guide
"Caprock Canyons State Park lies along what is known as the Caprock Escarpment, a long, slender formation of rock that demarcates the transition between the western High Plains (also known as the Llano Estacado) and the easterly Rolling Plains. The rocky escarpment is a thousand feet high in places and creates a stunning visual impact as it drops off flat agricultural fields into exposed red beds and arroyos of shales, sandstones, mudstones, and silt. Water from creeks and streams along the Llano Estacado once flowed along an endless expanse of grass before spilling over the Caprock Escarpment and draining into the Red, Brazos, and Colorado rivers. As water drained over the Escarpment it eroded away the soils and rock, revealing the region’s geologic past in exposed layers of varied coloration, each representing eons of Earth’s history."
