Bedout /bɪˈduː/, or more specifically the Bedout High, is a geological and geophysical feature centered about 250 km (160 miles) off the northwestern coast of Australia in the Canning and overlying Roebuck basins. Although not obvious from sea floor topography, it is a roughly circular area about 30 km (20 miles) in diameter where older rocks have been uplifted as much as 4 km (2.5 miles) towards the surface and may mark the centre of a very large buried impact crater up to 250 km (160 miles) in diameter.[1] The Bedout High was penetrated by two petroleum exploration wells (Bedout-1, Lagrange-1) in the 1970s and 1980s. It is named after nearby Bedout Island.
