Ice Age Floods *3 spots left*
Travel the path of the great Ice Age Floods from Missoula to Portland on this popular geology, birding, and wildlife tour. Our journey begins in western Montana, where a great lake once covered 3,000 square miles of land, before bursting through a massive ice dam and carving many of the geologic wonders we marvel at today. From the giant ripples of Camas Prairie to the astonishing channeled scablands of eastern Washington, the dizzying Grand Coulee and the awesome Columbia River Gorge, this tour keeps you in the flow throughout.
