Interstate State Park

Overview

Interstate State Park includes 293 acres of diverse plant and wildlife habitat. Established in 1895, it protects a unique landscape and globally-significant geology along the St. Croix River. A billion years ago, dark basalt rock formed here when lava escaped from a crack in the earth’s crust. Just ten thousand years ago, water from melting glaciers carved the river valley. Within that water were fast moving whirlpools of swirling sand and water that wore deep holes into the rock. Today, we call these holes glacial potholes and you can see more than 400 examples of them at the park.
