Animas River

The Animas River is a 126-mile-long river located in southwestern Colorado, USA. It flows through the San Juan Mountains and is known for its scenic beauty and recreational opportunities, including rafting and fishing. The river is significant for its historical role in mining, which has impacted its water quality. In 2015, a major environmental incident occurred when a mining wastewater spill turned the river bright orange, highlighting the challenges of pollution in the area. The Animas River ultimately merges with the San Juan River, contributing to the larger Colorado River system.
