Join Rock Creek Conservancy for our 8th Annual Rock Creek Extreme Cleanup. Volunteers will clean-up the lands, banks, tributaries, and waters of Rock Creek. Our goal is total stream cleanup of Rock Creek and its tributaries, the parks connected to Rock Creek, and the neighborhoods near Rock Creek where trash originates.  ::   Please dress appropriately for the weather. Wear sturdy boots or sneakers, no sandals.  ::  What to Bring - Trash bags and gloves will be provided. Feel free to bring your own tools and gloves if you have them.
