Whitmore Canyon Panorama
The road down Whitmore canyon is the closest you can drive to the river itself. From here there is a short, steep trail to the river, dropping 800 feet. If you look at the full-sized version of this pano, you can see the trail switchbacking down on the right side of the pano.
This is a three-photo pano made at 16mm focal length with a Canon 5Dii
Note the basalt rock in the foreground and also directly across the canyon. This lava flow at one time dammed the Colorado river, creating a natural lake. Eventually the dam was breached by erosion, restoring the river to its natural flow. There are several other places along the river that were dammed, and apparently there have been several cycles of volcanic events damming the river and then being eroded away.
