The Continental Divide divides the region into two large drainage areas. To the east of the Divide, waters, flow to the Arctic Ocean, to the Hudson Bay, or to the Atlantic oceans through the Mississippi River system. To the West, they flow into the Pacific Ocean. Hope this helps. ;)

The answer is - Sunspots.
Sunspots are dark in appearance, but only on a visible light, and this is due to the fact that they are much cooler than the surrounding areas, but that doesn't mean by any means that the sunspots are cool, on contrary, they are very hot too. Sunspots actually are storms that appear in the lower atmosphere of the sun.
