Mastodon and camel bones and artifacts from the Ice Age 12,000 years ago have been found at the Seminole Canyon State Park, but the park’s main attraction is the rock paintings that date from a period some 7,000 years later, after the climate had changed. Under rock shelters in the limestone riverbanks, ancient people painted enigmatic human-l ike and zoomorphic figures. Tours of two of the rock-shelter areas are available through the state park staff headquarters. The 2,172-acre park also contains part of the original route of the Galveston, Harrisburg and San Antonio Railway and remnants (including a bread oven) of the camp set up during its construction in 1882. The railroad route was moved in 1892, when a spectacular bridge (since demolished) crossing the Pecos was built.
