Channeled Scablands The Channeled Scablands were one of the first pieces of evidence that geologist J Harlen Bretz used to support his hypothesis that, unlike many areas of the world, the Pacific Northwest of the United States was in part carved rapidly by catastrophic flooding. Geologists originally thought that this area, once covered in a silt-like sediment called loess, was carved much like the Grand Canyon, over millions of years, because of the amount of material that had been eroded away. However, Bretz inferred that due to the erratic and inconsistent channels created, millions of years of gentle erosion could not have possibly carved through the silty topsoil and basalt flows underneath in such a way. Instead, these channels were carved when enormous glaciers dammed water in Montana; eventually the water overtopped the ice dam, causing it to break apart and catastrophically releasing the water. -EF and JBB Image credits: EF

We skated the Bonneville Salt Flats and put big rusty bites in our bearings. It was like skating on a different planet.
