Smith Rock Shelter, Archaeological site at McKinney Falls State Park, Austin, Texas.

Smith Rock Shelter is a natural limestone overhang that abuts Onion Creek in McKinney Falls State Park near Austin, Texas. The overhang forms a dry, sheltered recess in the rock where soil deposits have preserved traces of human use from about 500 BCE into the 18th century.

Native Americans used this limestone overhang from about 500 BCE until the 18th century. The last known occupants were related to the Tonkawa. The shelter was added to the National Register of Historic Places on October 1, 1974.

The shelter's last known occupants were related to the Tonkawa, whose presence here marks the final chapter of its long use before the 18th century. Visitors can see the limestone overhang itself, the feature that drew people to this spot beside Onion Creek for roughly two thousand years.

The shelter is reached by the Smith Rockshelter Trail, a 0.8-mile (1.3 km) round trip from the trailhead in McKinney Falls State Park. The path leads to the limestone overhang above Onion Creek; stay on the marked route to keep the archaeological deposits undisturbed.

This is one of only two documented rock shelters in Travis County listed on the National Register of Historic Places. This distinction highlights how rare and important such archaeological sites are for understanding central Texas history.
