We traverse the complex of canyons encompassing Coal Creek and Upper Crab Creek. Breathtaking formations were created nearly 17.5 million years ago by active volcanic craters pouring fourth huge lava flows building layers upon layers of lava now cooled into layers of basalt rock. Over 100 open craters are now visible as ring-diked craters. Other views take in formations created by the great Lake Missoula Flood of some fifteen thousand years ago, and by earlier and similar floods. The resulting Channeled Scablands tell a
remarkable story written on the pages of geological prehistory; and demonstrating the massive and dramatic power of nature unleashed.
