Makoshika State Park is the largest of Montana's state parks at more than 11,000 acres (45 km²). It is located east of Glendive. The park contains spectacular badlands which conceal dinosaur fossils. The park contains rock from the Hell Creek Formation and dinosaurs such as Triceratops are found there. In 1997, a fossil Thescelosaurus was found at Makoshika by an expedition led by Jack Horner and Bob Harmon. Birds such as turkey vultures, prairie falcons and eagles make their homes here.
