The huge Darwin Crater, approx. 1 km across and 200 m deep,was created about 73,000 years ago when a meteorite struck Tasmania near Mt.Darwin. The heat generated by the explosive force of the impact melted andvaporized the rocks. The molten material was hurled into the sky, falling backas glass and creating one of the world\'s most spectacular silica glass fieldsassociated with a meteorite crater.

The geologist Lostus Hill found in 1915 small pieces ofimpactite glass about 10 km west of the crater but could not pinpoint thesource of it. In 1972 R.J. Ford, a geologist at the University of Tasmania,found the crater in dense bush whilst working on an access road for the thenproposed Gordon-below-Franklin Dam for the Hydro-Electric-Commission. Thecrater floor is covered by thick tea-tree swamp. In 1974 a 4WD track wasbulldozed into the crater to allow a drill hole being put down in the center.This showed that in the past 73,000 years the crater has completely been filledwith sediment, which provides a valuable pollen record revealing the changingvegetation of the area.
