The Yellowstone River Cleanup is the longest running (19 years) and largest (over 370,000 lbs) cleanup in Montana. We work 11 months out of the year and cover more than 125 river miles. The community cleanup is attended by over 100 people each year and regularly results in the removal of over 10,000 lbs.
