[2] The Rio Grande Gorge and its river follow a topographical low within the larger Rio Grande Rift; a mixture of volcanic activity, shifting tectonic plates, and erosion of layers of gravels and lava yielded the recognizable narrow, deep gorge visible today.
[3][4][5][6] The canyon ecosystem descends 800 feet (240 m) from rim to river, creating a unique diversity in plant and animal life.
Wildlife include mule deer, red-tailed hawk, mountain blue-bird, prairie dog and big horn sheep.
The climate is semi-arid with summer thunderstorms common in July and August, and snow possible from November through March.
The Wild and Scenic River flows through the Rio Grande Gorge Recreation Area.
