Ice Age Floods Evidence Mt Tabor Park

Rounded rocks and boulders, encased in a matrix of mud and roots, exposed in the root ball of a storm-toppled 120-year-old fir tree atop Mount Tabor Park. This is perfectly preserved evidence of the Ice Age Floods (aka Missoula Floods), cataclysmic glacial lake outburst floods that swept down the Columbia River Gorge at the end of the last ice age, strewing flood-transported moraine rocks across across the landscape, even to elevations of 600 feet (200m) above river level. Portland, Oregon, USA.
