Seminole Canyon State Park & Historic Site


Diverse flora and fauna throughout the park include white-tailed deer, raccoons, armadillos, and squirrels. There is sparse vegetation, the terrain is rocky, and there are deep canyons.

Seminole Canyon is still being created - deepened and widened year after year. The erosive forces of rain and flood continue to expose rock deposited up to 100 million years ago, during the Age of Dinosaurs. Ancient inland seas repeatedly flooded the landscape and then withdrew, laying down alternate bands of clay from the land and lime from the ocean. This process resulted in the layer cake of rock sequences visible today.

During the Pleistocene ice age (12,000 – 10,000 years ago), the region’s temperate climate supported lush vegetation that included pine, juniper and oak woodlands in the canyons and luxuriant grasslands on the uplands. Ice Age hunters pursued now-extinct species of elephant, camel, bison and horse across the plains.

By 7,000 years ago, the ever-drying landscape resembled that of today. A new culture emerged in this changed environment. The Archaic people lived in the dry rock-shelters that line the canyon walls and subsisted on many of the same arid-adapted plants and small animal species that inhabit the park today.
