They are large volcanic craters that form by two different methods: 1) an explosive volcanic eruption; or, 2) collapse of surface rock into an empty magma chamber.. Wizard Island is the top of one of the cones. For comparison, the famous caldera of Yellowstone in Wyoming is only about 60 km (37 miles) wide. It may be the world's largest known caldera with a diameter of ~150 km (93 miles). Calderas are some of the most spectacular features on Earth. Crater Lake is located within the collapsed caldera of Mount Mazama on the crest of the Cascade Range in southern Oregon about 90 km (55 mi) north of the city of Klamath Falls and about 100 km (60 mi) northeast of Medford.

Its heavily forested rim An impact crater with depth to diameter ratio comparable to Siloe Patera would be expected to show these features – unless perhaps the crater had undergone extensive erosion or modification – but it does not. A CALDERA is a large depression in a volcano formed either by the collapse of the top of a composite volcano after an explosive eruption, or from the collapse of the top of a shield volcano after the magma chamber is drained. Sometimes lakes which form inside calderas are called caldera lakes, but often this distinction is not made The caldera measures between 10 and 12 miles (16 and 19 km) across and has an area of 102 square miles (264 square km). Volcanism continued after the caldera formed. Mazama, violently erupted. Llao Rock forms the step cliff along the caldera wall in the top left of … Learn vocabulary, terms, and more with flashcards, games, and other study tools. For several thousand years after this eruption, smaller volcanic eruptions continued inside the caldera. One of these eruptions was so large it formed an island in Crater Lake named Wizard Island.
