The Boquillas Canyon Overlook gives an amazing view of the Rio Grande, which carved the dramatic Boquillas Canyon.
An interpretive sign at the overlook reads as follows:
"BOQUILLAS CANYON
The massive cliffs of the Sierra Del Carmen appear unyielding, yet the Rio Grande is carved to Gorge 1300 feet deep directly through the escarpment. Boquillas Canyon is so narrow that the entrance is almost invisible at this distance.
From the trailhead 1 mile down the road, hike the short Boquillas Canyon trail to the canyon entrance. Beside the water, between towering walls, you can see and hear how water acts as a liquid rasp, grinding the gorge deeper with tons of silt and sand.
Canyon cutting
the Rio Grande established its present course on basin filling sediments that covered the rocks and faults we see exposed today. The river eroded through the surface layers and cut the steep sided canyons in the more resistant Lower Cretaceous limestones. Today you can see those ancient limestone formations exposed in the canyon walls.
