Uzon Caldera

It is a pit-like crater of 9x12 km size; it is one of the biggest calderas in Kamchatka. The top point of the caldera edge is the Baraniy peak (1617 m over the sea level); the bottom is at 650-700 m over the sea level. The caldera was formed about 40 thousand years ago. In the east part of the caldera there is one of the greatest explosion craters in Kamchatka - it has the diameter of 1,65 km and is filled with the waters of the Dalnee Lake (Far Lake). The west part of the caldera is swamped. There are several lakes in that part, the biggest one is the Central Lake, which gathers the water from all caldera. In the west and the north the caldera is surrounded by the ridge - the remnants of an ancient volcano.
