Geologists say that the Twin Sisters basalt rock formation and popular rock climbing spot near Wallula, Wash., seen June 3, 2000, are a result of erosion from a great flood near the end of the last Ice Age, 12,000-15,000 years ago. The National Park Service is proposing to set up interpretive sites in Montana, Idaho, Washington and Oregon, which would include significant features, including the Twin Sisters, along the flood's path to help explain the story of the Ice Age floods and their impact on today's landscape.

Devil's Towers
The nearly vertical monolith known as Devils Tower rises 1,267 feet above the meandering Belle Fourche River. Once hidden below the earth's surface, erosion has stripped away the softer rock layers revealing Devils Tower.
Known by several northern plains tribes as Bears Lodge, it is a sacred site of worship for many American Indians. The rolling hills of this 1,347 acre park are covered with pine forests, deciduous woodlands, and prairie grasslands. Deer, prairie dogs, and other wildlife are abundant.
Proclaimed September 24, 1906 as the nation's first national monument by President Theodore Roosevelt.
Absolutely fascinating book on the subject with lots of information about J. Harlen Bretz and his battle to have his theory recognized.
Accumulation of large basaltic boulders downstream of plunge pools at Dry Falls State Park. Dry Falls is a great cataract 3.3 miles wide and 396 feet high that formed during the cataclysmic late Pleistocene floods emanating from glacial Lake Missoula in Montana. The origin of the Channeled Scablands was the subject of one of the most famous controversies in the history of geology. When J. Harlen Bretz formulated the cataclysmic flood hypothesis in 1923, his ideas were rejected. Nearly 50 years passed before his ideas became a standard of geologic thinking. In 1979 and at nearly 90 years of age he was awarded the Penrose Medal of the Geological Society of America, the nation's highest geological award.

I'll bet that erosion was triggered by logging.
I'm thinking that the public has a lot more things to think about. Things like "How much is THIS stupid idea going to cost me...."
