Lv 5. Crater lakes covering active (fumarolic) volcanic vents are sometimes known as volcanic lakes, and the water within them is often acidic, saturated with volcanic gases, and cloudy with a strong greenish color.
Crater Lake in Oregon is a fine example.

Although Crater Lake has been dormant for about 5,000 to 6,000 years, there could be another eruption someday in the future and Mount Mazama might grow back. The low-rimmed Kurile Lake caldera was formed in two stages during the late Pleistocene and early Holocene. However, there is some disagreement between scientists about the definition of what an extinct, dormant and active volcano is.

It is part of the area of the "east Eifel volcanic field". The long history of volcanism at Mount Mazama strongly suggests that this volcanic center will be active in the future.
The man fell 800 feet down into the caldera near Rims Village, the US Coast Guard said. For example, the crater lake of Kawah Ijen in Indonesia has a pH of under 0.5. The little islands are formed by fumeroles, small gas release cones inside the main crater. The name refers to Mount Tabor, Israel . 2 hours ago Report. (CNN)A person was rescued Monday after falling into Oregon's Crater Lake -- a dormant volcano.

Kurile Lake caldera is one of the most impressive volcanic features in Kamchatka.

Ijen volcano in East Java contains the world's largest acidic volcanic crater lake, called Kawah Ijen, famous for its turquoise color. The descriptions of volcanic craters go on, and on. Both Brown and Leg of Mutton lakes are dry in recent years, due to the lowering of the water table. Laacher See or Laach Lake (in English) is a crater lake or more exactly a caldera lake in the Rhineland-Palatinate, Germany, situated close to the cities of Koblenz, Mayen (11 km), and Andernach (14 km). The crater inside the extinct volcano named Diamond Head in Hawaii is home to a small military base. Also significant are many faults near Crater Lake that clearly have been active in the recent past. Crater lake may refer to: Impact crater lake; Volcanic crater lake; Crater Lake (disambiguation) This disambiguation page lists articles associated with the title Crater lake. Crater Lake partly fills one of the most visually spectacular calderas of the world, an 8-by-10-km (5-by-6-mi) basin more than 1 km (0.6 mi) deep formed by collapse of the volcano known as Mount Mazama during a series of explosive eruptions about 7,700 years ago. Although Crater Lake has been dormant for about 5,000 to 6,000 years, there could be another eruption someday in the future and Mount Mazama might grow back.
