Pictograph Cave State Park [MT]
The Pictograph, Middle, and Ghost cave complex was home to generations of prehistoric hunters. Over 30,000 artifacts have been identified from the park. A short paved trail allows visitors to view the rock paintings, known as pictographs, that are still visible in Pictograph Cave, the largest of the three. Interpretive signs tell the story of Montana's first professional archaeological studies and excavations.
