Boulders Along the Shoreline at Tettegouche State Park
Rocky shoreline with ancient volcanic rocks at Tettegouche State Park on Lake Superior's North Shore.
Tettegouche State Park runs along nearly six miles of Lake Superior's North Shore in Minnesota, covering more than 9,000 acres of boreal forest, inland lakes, and volcanic rock cliffs. The rocky shoreline is made up of rhyolite and basalt formations dating back over a billion years to the Midcontinent Rift, when lava flows shaped much of the region's bedrock. Lake Superior holds roughly 3 quadrillion gallons of water, making it the largest freshwater lake in the world by surface area. The park was established in 1979 on land once used for logging operations and a private fishing retreat.
