The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
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.
