Dimensions and Depth
The lake is 5 by 6 miles (8 by 10 km) across with an average depth of 1,148 feet (350 m). Its maximum depth has been measured at 1,949 feet (594 m), which fluctuates slightly as the weather changes. On the basis of maximum depth, Crater Lake is the deepest lake in the United States, the second deepest in North America, after Great Slave Lake in Canada, and the ninth deepest lake in the world (Lake Baikal is the deepest). Crater Lake is often cited as the seventh deepest lake in the world, but this ranking excludes Lake Vostok, which is situated under nearly 13,000 feet (4,000 m) of Antarctic ice, and the recent soundings of San MartÃn Lake, which is located on the border of Chile and Argentina.
However, on the basis of comparing average depths among the world's deepest lakes, Crater Lake becomes the deepest lake in the Western Hemisphere and the third deepest in the world. Comparing average depths among the world's lakes whose basins are entirely above sea level, Crater Lake is the deepest.
The caldera rim of Crater Lake ranges in elevation from 7,000 to 8,000 feet (2,100 to 2,400 m).

Famous quotes containing the words dimensions and/or depth:
“I was surprised by Joe’s asking me how far it was to the Moosehorn. He was pretty well acquainted with this stream, but he had noticed that I was curious about distances, and had several maps. He and Indians generally, with whom I have talked, are not able to describe dimensions or distances in our measures with any accuracy. He could tell, perhaps, at what time we should arrive, but not how far it was.”
—Henry David Thoreau (1817–1862)
“From the depth of the dreamydecline of the dawn through a notable
nimbus of nebulous noonshine,”
—A.C. (Algernon Charles)
