The Mount Hypipamee Crater, also known as The Crater is a huge diatreme located south-east of Herberton on the Atherton Tableland in Far North Queensland, Australia. It is 61 metres in diameter and 82 metres deep. It was first discovered by accident when in 1879 Weate and party nearly fell into it. They were heading towards the Mulgrave River on a five month gold prospecting expedition. The national park was established in 1908 under the sponsorship of a Mr. Ringrose of Herberton. There was a debate at the “crater trust” meetings during the 1930s as to what to call “the crater”, the "Herberton Crater" was one suggestion but it was decided to call it the traditional Dyrbal name, Mount Hypipamee. A request was written to Ernest Gribble of Palm Island to find the origin of the name. The name Hypipamee is a corruption of the Aboriginal word, nabbanabbamee, which is connected with a legend of two young men who cut down a sacred candlenut tree, only to be swallowed up by a large hole in the earth, the crater. The water surface is covered with duck weed. Dinner Falls at the head of the upper Barron River gorge is also part of this park. It was once thought that "The Crater", Lake Eacham and Lake Barrine were all connected underground with water tunnels, but this is incorrect. Local legend once said that an aboriginal woman once fell over the side into the crater and later surfaced in Lake Eacham. A diatreme, sometimes known as a maar-diatreme volcano, is a volcanic pipe formed by a gaseous explosion. When magma rises up through a crack in the Earth's crust and makes contact with a shallow body of ground water, rapid expansion of heated water vapor and volcanic gases can cause a series of explosions. A relatively shallow crater is left (known as a maar) and a rock filled fracture (the actual diatreme) in the Earth's crust. Diatremes breach the Earth's surface and produce a steep inverted cone shape. The term diatreme has been applied more generally to any concave body
