Mt Hypipamee

The Hypipamee crater is referred to as a volcanic pipe. The pipe was opened upward through surface rocks by gas produced from molten rock below and as a result of tremendous pressure, the vent exploded sending volcanic bombs far across the landscape. It has a diameter of 61 metres at the water level which is 58 metres below the platform. Even 85 metres below the water surface, the pipe hasn't lost any of its dimensions.
