The rock art and artifacts found at Pictograph Cave State Park provide a look into the lives of the area’s first residents. For nearly 10,000 years the caves have been used by humans who left drawings on the walls and signs of daily life in the caves. Three alcoves, or “caves” make up the park but only one holds pictographs. A trail leads from the visitor center to the alcoves and the park can be visited in an hour or so. The park is just 5 miles from I90 and Billings, MT and is definitely worth a visit.
