As water flows south through the River des Peres Watershed in St. Louis, trash, tires and metal gets deposited along the way. Over the weekend, hundreds of volunteers worked to pick up all that trash during the sixth annual cleanup called the River des Peres Trash Bash.
At Gravois Creek on Saturday morning, about a dozen volunteers stacked muddy tires into a trailer hitched to a four-wheeler.
Earlier, volunteers had fished the tires out of the creek using canoes. By mid-morning, volunteer Doug Geist estimated that they had collected more than twenty tires.
