Rain falls on two hills, runs down both slopes and drains into the same river, and the land between the hilltops lights up as that river's watershed, with the hilltops marked as its edges. Rain that lands just past a hilltop runs down the other side to another river, a home by the river shows that we all live in a watershed, and the video ends on the recap that land that drains to one river is a watershed.
