(PhysOrg.com) -- Ambling through the parched and scarred landscape of eastern Washington state is the 60-mile-long Grand Coulee, the largest of the stair-step canyons that give the region called the Channeled Scablands its character.

The flood, which continued for six weeks, stripped the valley of mesquite, oak trees, and soil; destroyed a bridge; and plucked meter-wide boulders from the ground. And, in a remarkable demonstration of the power of raging waters, the flood excavated a 2.2-kilometer-long, 7-meter-deep canyon in the bedrock. http://phys.org/news196255219.html Space & Earth Sun, 20 Jun 2010 13:00:01 EST news196255219 (PhysOrg.com) -- New research indicates that one of the largest fresh-water floods in Earth's history happened about 17,000 years ago and inundated a large area of Alaska that is now occupied in part by the city of Wasilla, widely known because of the 2008 presidential campaign. http://phys.org/news191683663.html Space & Earth Wed, 28 Apr 2010 14:28:08 EST news191683663
