Rollin’ through the Ice Age.
The Tonquin Trail — a 22 mile system of paths that will someday connect the cities of Sherwood, Tualatin and Wilsonville — is now officially named the Ice Age Tonquin Trail. The project has also just completed a master plan that is set to be forwarded onto city, regional, and county officials after a slate of public hearings early next year.
About 12,000 to 17,000 years ago, the same cataclysmic floods that started in Montana and created the Columbia River Gorge, also spilled into the Willamette Valley and left an a geologic imprint that remains today. The National Park Service has recognized the path of these floods and passed the Ice Age Floods National Geologic Trail into law in 2009.
