Crater Lake in the southern Cascade Range of Oregon, USA, is one of the most beautiful calderas in the world. It formed by the collapse of a massive stratovolcano known as Mount Mazama about 6850 years ago. The caldera measures 8x10 km in diameter and is filled with a lake of up to 600 m depth.
A small island, Wizzard Island, is a cinder cone that grew after the formation of the caldera. The caldera is part of Crater Lake National Park.
Ethiopia and the Danakil: Ethiopia is a very diverse and beautiful country. Thanks to our numerous expeditions to Erta Ale and Dallol and beyond, we have an extensive collection of images showing the volcano's lava lake, the desert, the colorful hot springs of Dallol, the vast salt lakes, camel caravans and more.
Tours to active volcanoes: Watching a volcanic eruption is one of the most impressive natural displays. We have a wide selection of tours to active volcanoes worldwide at different activity and difficulty levels.
