Crater Lake is a caldera lake located in the south-central
region of the U.S. state of Oregon. It is the main
feature of Crater Lake
National Park and famous
for its deep blue color and water clarity. The lake partly fills a nearly 2,148
foot (655 m) deep caldera that was formed around 7,700 (± 150) years ago by the
collapse of the volcano Mount Mazama.
On June 12, 1853, John Wesley Hillman was reportedly the
first person of European descent to see what he named “Deep
Blue Lake”
in Oregon.
The lake was renamed at least three times, as Blue
Lake, Lake
Majesty, and finally Crater
Lake.
Crater Lake is known for the “Old Man of the Lake”, a full-sized tree which is now a stump that has
been bobbing vertically in the lake for more than a century. Due to the cold
water, the tree has been rather well preserved.
While having no indigenous fish population, the lake was
stocked from 1888 to 1941 with a variety of fish. Several species have formed
self sustaining populations. Since 2002, one of the state’s regular-issue
license plate designs has featured Crater Lake.
The commemorative Oregon State Quarter, which was released by the United States
Mint in 2005, features an image of Crater Lake
on its reverse.
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. This makes Crater Lake the deepest
lake that is completely in the United States,
the second deepest lake in North America, and
the ninth deepest lake in the world
