Take in the view of this void from the Rio Grande Gorge Bridge on Highway 64, a piece of engineering to match the drama of the canyon itself. Way below is a river that promises white-water rafting par excellence.
Underground volcanic activity still shows up in hot springs along the valley, and petroglyphs reveal human activity from centuries past.
The Rio Grande Gorge is a geological feature in northern New Mexico where the watercourse of the Rio Grande follows a tectonic chasm. Beginning near the Colorado border, the approximately 50-mile (80 km) gorge runs from northwest to southwest of Taos, New Mexico, through the basalt flows of the Taos Plateau volcanic field. The gorge depth is 800 feet (240 m) just south of the Rio Grande Gorge Bridge, which spans the gorge 10 miles (16 km) northwest of Taos. Wikipedia
