Another collection of air and space imagery has been compiled by Koeberl and Sharpton as Slide sets. Interior Australia is the home of perhaps the most dramatic exposure of the central peak of a complex crater anywhere in the world, seen below in this aerial oblique view of a ringed mountain at the Gosses Bluff Crater. They have since been breached so that the lower interior now exposes softer rocks being eroded. In the Large Format Camera photo below, taken from the Shuttle, this central peak stands out in sharp contrast to the folded rocks of the McDonnel Range to its north. Erosion nearly obliterated the outer sections of the crater, but they are faintly expressed as a dark band in the photo.
Water often fills complex craters sufficiently intact to retain a central depression.
The aerial oblique view offers a different perspective. The Elgygytgyn Crater interior, defined by the lake, seems almost squarish rather than round. Speculate on the cause of this departure from the normal inner shape of impact craters. In these rocks, much of the feldspar has transformed by shock into glass, known as maskelynite. Because of this contrasting surface expression, astronauts journeying back from the Moon could see this crater from well out in space.
