Green River

Green River is a town in Sweetwater County located along the river of the same name in southwestern Wyoming's high desert landscape. The town sits at an elevation of about 1,864 meters (6,100 feet) and is surrounded by the dry terrain and wide horizons typical of the region.

The town began to develop after the Union Pacific Railroad arrived in 1868, making it a key distribution hub for the region. It was formally incorporated as a city in 1891 as growth continued with the expansion of mining operations.

The town sits along the river that gives it its name, a waterway that has shaped settlement patterns and local identity for generations. People here maintain a strong connection to the landscape through outdoor activities and regional pride in their position along this significant natural feature.

Visitors should prepare for the dry, sunny climate of the high desert and bring appropriate clothing for temperature swings. The town provides a good base for exploring the surrounding landscape, where hiking and outdoor activities are easily accessible from the main area.

The surrounding area holds extensive fossil deposits from the Green River Formation that preserve detailed records of ancient lake ecosystems. These fossils document past life and extinct species from millions of years ago, making the region significant for paleontological study.
