Tower Rock State Park

Tower Rock State Park is a state park near the community of Cascade in the U.S. state of Montana in the United States. The centerpiece of the park is Tower Rock, a -high rock formation which marks the entrance to the Missouri River Canyon in the Adel Mountains Volcanic Field. It was well-known to Native Americans, and considered a sacred place by the Piegan Blackfeet. Tower Rock received its current name when Meriwether Lewis of the Lewis and Clark Expedition visited the site in 1805. Railroad and highway development in the late 1800s and 1900s skirted Tower Rock, but the landform itself remained pristine. The encompassing Tower Rock was added to the National Register of Historic Places on March 18, 2002. The Tower Rock State Park was created around the National Historic Site in 2004.
