The Virtual Rowena Crest Cache is located on the historic Gorge Highway. It will take your breath away.
One of the interesting facets of the game is the introduction of folks to geographic areas, terrain features and historic sites they may never have seen.
Ice Age floods, volcanism, uplift, erosion and human endeavor have indelibly etched the Columbia River Gorge. But cataclysmic floods during the twilight of the Last Ice Age (1200 to 1500 years ago) affected the landscape more than any other terrestrial force, creating the scablands called The Rowena Plateau.
As a massive ice sheet advanced from Canada, it dammed rivers with up to 2000 feet of glacial ice creating huge lakes across Idaho and Montana. The largest of these, 3000 square mile Lake Missoula, held over 5000 cubic miles of water - half the volume of Lake Michigan. When the rising waters undermined these ice dams, tremendous floods swept across the land and down the Columbia River Basin. Torrents of ice and water raged downstream as many as 100 times, scouring away soils at elevations up to 1000 feet!
E-mail us with the name of the geologist who wrote in 1986 --Imagine water blasting from a fire hose.... and also tell us the name of the city in Washington which is built on a huge gravel bar left by the cataclysmic Ice Age Floods.
