Moab Fault:
A dramatic break in the earth's surface occurred here about six million years ago. Under intense pressure, unable to stretch, the crust cracked and shifted. Today, the highway parallels this fracture line, called the Moab Fault.
After the rock layers shifted, the east wall of the canyon where you are standing ended up more than 2,600 feet lower than the west side (across the highway). |
