The Fremont Indians, people who lived at the same time as the Anasazi culture, occupied this area until sometime before 1300 A.D. They were first hunter gatherers, but also learned to farm these arid lands by building rock checkdams and directing rainwater to catchment crop areas. Fremont people were influenced by their neighbors, but they were also distinctly different. Like the Anasazi to the south, they had the bow and arrow, pottery, and basketry. Dinosaur National Monument, Utah.
