Starting at the top of the Continental Divide in the US, Drop follows the westward path of a single drop of water until, around 1,500 winding miles later, it spills into the Pacific Ocean. Along the way, we meet the men and women who live, work and play on these rivers—people who work tirelessly to ensure that these waters, and all they support, are healthy. Through this dedication, hard work, and passion, Drop illustrates how the water connects us all.
