A true cosmic phenomenon on earth…The Snake River Plains have been forming for millions of years from numerous geologic and natural events. The most recent is the Bonneville Flood some 14,500 years ago, that provides the current beautiful scenic attributes.


Lake Bonneville, the precursor to the Great Salt Lake, once nearly 1,000 feet above the current level and resting on the higher slopes of the surrounding mountains, nearly 20,000 square miles in size - raptured its shores and discharged an immense volume of water to the north and then west down the Snake River.


It is calculated that the Snake River sustained a high rate of flow from the flood for more than one year.


Present-day Devil’s Corral was formed at this time. At the mouth of Devil’s Corral, resistance from the lava rock formation forced the water to be backed up temporarily. Swerving violently around, like a cornered Tasmanian Devil trying to find an exit, the force of the water and suspended rocks formed the magnificent canyons in Devil’s Corral before it continued on its journey to the Pacific Ocean. When the water receded, two new rivers and majestic rock canyons were left behind as a reminder of the beautiful art nature can create!
