The Channeled Scablands are a barren, relatively soil free landscape in eastern Washington, scoured clean by a flood unleashed when a large glacial lake drained. They are a geologically unique feature in the U.S. They were created by the cataclysmic Missoula Floods (reaching flow speeds in excess of 65 mph!) that swept periodically across eastern Washington and down the Columbia River Plateau during the ice age. Planetary scientists have taken note of the these lands as they are the best terrestrial analog for the Martian outflow channels.
Around 15.5 million years ago, the region was lush and wet, home to many plant species now extinct. A number of trees were buried in volcanic ash, and the organic matter in the tree trunks was gradually replaced by minerals in the groundwater; the resulting petrified wood was protected for millennia by flows of basalt. The catastrophic Missoula Floods eroded the basalt, exposing some of the petrified wood. Additionally, remains of prehistoric animals and early natives have been found here. Most notably a Blue Rhinoceros that had been entombed in a lava flow.
GrizzLee spent 3 days solo exploring, camping and hiking the area via motorcycle.
