The Triangle Oil & Historical Museum features a wide selection of Cleveland and Pawnee County memorabilia as well as exhibits on early oil field work in the area. The history of the Triangle Region includes the area bordered by the old Pawnee reservation and the Arkansas and Cimarron Rivers.
Also on the grounds is the relocated Sneed Cabin. The original Sneed Cabin built in 1899 is one of the oldest log houses in Oklahoma. It was built by Everett and Mandy Sneed. Etched in one of the rocks at the top of the chimney is the date, Sept. 1900.
