The Green River Basin is a large geological area located in southwestern Wyoming, known for its rich natural resources and unique landscapes. It is primarily characterized by its sedimentary rock formations, which contain significant deposits of fossil fuels, including coal, oil, and natural gas. The basin is also home to the Green River, which flows through the region, providing vital water resources for both wildlife and human activities. This basin is part of the larger Rocky Mountain region and features diverse ecosystems, including sagebrush steppe and riparian habitats. The area is significant for its paleontological sites, where fossils from the Eocene Epoch have been discovered, offering insights into ancient life. The Green River Basin is also important for recreational activities, such as hiking, fishing, and wildlife viewing.
