On-water cleanup opportunity:
Volunteers will have the opportunity to clean up trash from Mosenthein Island on the Mississippi River, a small wilderness island in the heart of north St. Louis. Missouri River Relief will shuttle volunteers by motor boat to the island, where they will gather trash washed in by last year’s floods for removal.
