Much of the trail passes through ponderosa pine forests; in other places the path crosses meadows or traverses mesas with desert plants like agave.
The route over the mesa provides a dramatic contrast in landscape, climate and vegetation.
Also, studies of the thermal inertia suggest that the mesa and the walls of the canyon are made of different substances.
This peak is standing alone in a land of mesas, and is easily seen from a distance between cliffs and canyons.
The area is filled with beautiful mesas, deep narrow canyons, and fjord-like lakes.
All the mesas are volcanic in origin caused by lava flows which solidified into basalt.
Some groups on the region's mesas developed irrigation techniques, and filled storehouses with grain as protection against the area's frequent droughts.
