Mount Hood, the tallest mountain in Oregon, has a secret, scientists revealed. Covered by trees and plants is an earthquake fault that stretches for miles from the iconic mountain.
The fault appears to have been recently active, and could be an earthquake threat today, reported the Portland Oregonian. Scientists said the last time the fault ruptured, possibly as a magnitude 6 or 7 earthquake, the ground ripped six feet (1.8 meters) apart.
The fault was discovered by scientists flying over Mt. Hood using lasers to scan the terrain. The fault is about 20 miles (32.2 kilometers) long and stretches from the northern flank of Mount Hood to the Columbia River.

Lidar imaging revealed another fault near Mount Hood that runs to within a mile or two of the Columbia River Gorge, which raises questions about the earthquake resistance of hydropower dams. "None of the dams were designed with this kind of fault in the analysis," Madin says.
