Geologic map of the lake floor Crater Lake from space. Mount Mazama, part of the Cascade Range volcanic arc, was built up mostly of andesite, dacite, and rhyodacite over a period of at least 400,000 years. The caldera was created in a massive volcanic eruption between 6,000 and 8,000 years ago that led to the subsidence of Mount Mazama.
Crater Lake is often referred to as the seventh-deepest lake in the world, but this former listing excludes the approximately 3,000-foot (910 m) depth of subglacial Lake Vostok in Antarctica, which resides under nearly 13,000 feet (4,000 m) of ice, and the recent report of a 2,740-foot (840 m) maximum depth for Lake O'Higgins/San Martin ...
The Old Man of the Lake in 2013. The Old Man of the Lake is a 30-foot (9 m) tall tree trunk, most likely a hemlock, that has been bobbing vertically in Crater Lake in Oregon, United States since at least 1896. The trunk is about 2 feet (61 cm) in diameter at the waterline and stands approximately 4 feet (1.2 m) above the water.
Crater Lake is called Giiwas in the Klamath language. [7] Steel had helped map Crater Lake in 1886 with Clarence Dutton of the United States Geological Survey. The conservation movement in the United States was gaining traction, so Steel's efforts to preserve the Mazama area were achieved on two scales, first with the creation of the local ...

The highway approaches Crater Lake National Park from the south, and is known as the Crater Lake Highway. While the highway is signed east-to-west, it is in reality shaped somewhat like a horseshoe; heading north-northeast from Medford, turning east as it approaches the park, and then turning south-southeast as it approaches Klamath Falls.
Rim Drive is a scenic highway in Crater Lake National Park in southern Oregon, United States.It is a 33-mile (53 km) loop that follows the caldera rim around Crater Lake.Due to its unique engineering and the surrounding park landscape, the drive was listed as a historic district on the National Register of Historic Places in 2008.
Mount Scott is a small stratovolcano and a so-called parasitic cone on the southeast flank of Crater Lake in southern Oregon. [4] [5] It is approximately 420,000 years old. [3] Its summit is the highest point within Crater Lake National Park, and the tenth highest peak in the Oregon Cascades. [6]
