Volcanic Cliffs Along Tettegouche State Park’s Lake Superior Shore
Rocky shoreline with ancient volcanic rocks at Tettegouche State Park on Lake Superior's North Shore, Minnesota.
Tettegouche State Park runs along nearly six miles of Lake Superior's North Shore in Minnesota. The dark rock along this stretch formed from volcanic activity roughly 1.1 billion years ago, part of the Midcontinent Rift that shaped much of the region's bedrock. Established in 1979, the park covers more than 9,000 acres and includes the Baptism River, which empties into Lake Superior nearby. It's also home to High Falls, the tallest waterfall located entirely within Minnesota's borders.
