The Colorado BLM cultural resources program is diverse and encompasses prehistoric sites dating from 12,000 years ago. There are more than 50,000 recorded prehistoric sites on Colorado's public lands. In addition, there are numerous nationally significant historic sites that represent mining, transportation, and western settlement. Colorado has six Adventures in the Past sites/tours available to the public.
The Anasazi Heritage Center (AHC), near the town of Dolores, houses several million artifacts, and includes exhibit areas and a laboratory. The AHC is the center of the BLM's Heritage Education Project, which is designed to provide information about the value of our culture.
In addition to its archaeological and historical resources, Colorado is the location for several internationally known paleontological quarries. Garden Park, near Cañon City, is one of the most significant localities for dinosaurs in the world, while the Rabbit Valley site in the Grand Junction area has yielded several new species.
