Muir and Riggs Glaciers, Muir Inlet, Alaska
Glaciers
As this picture of Muir and Riggs Glaceris in Alaska shows, glaciers are really rivers, but rivers of solid ice instead of liquid water. Just because they are solid does not mean they don't move, though. Glaciers do flow downhill, just very, very slowly.

How Ground Water Occurs
Lake Baikal from space, the largest, oldest, and deepest lake
Lake Baikal is the largest, oldest, and deepest freshwater lake in the world
Lake Baikal, the world’s oldest and deepest freshwater lake, curves for nearly 400 miles through south-eastern Siberia, north of the Mongolian border. At its deepest point it is over 5,000 feet (1,637 meters) deep.
