Jay Cooke State Park Professional Review and Guide
"A 126-foot swinging suspension footbridge crosses the St. Louis River, high above the gorge with its red clay banks--clay deposited long ago by Glacial Lake Duluth, the ancient glacial lake that later became Lake Superior. This bridge, rebuilt in 1953, was the only way across the river from the Thomson Hydroelectric Station powerhouse in the early 1900s. Since that time, the bridge has been modified, destroyed by weather, and rebuilt.
Jay Cooke State Park’s 50 miles of hiking trails follow this turbulent portion of river for a distance, take you across the footbridge past several scenic overlooks, and connect with the paved Willard Munger State Trail. Silver Creek, which drains into the St. Louis, is spring fed and stocked with trout. Beaver find its running water inviting. The evidence is in the fresh cuttings lying near their dams along the creek. Silver Creek Trail is part of the Minnesota Hiking Trail system."
