pretty good overlay for Barringer crater Arizona.
EDIT: hi-res imagery on GE, Overlay not the best fited. The Meteor Crater, sometimes known as the Barringer Crater and formerly as the Canyon Diablo crater, is a famous impact crater, located about 35 miles (55 km) east of Flagstaff, near Winslow in the northern Arizona desert (USA). The crater is somewhat misnamed, as it was actually excavated by a meteorite, not a meteor.
The crater is about 1,200 m (4,000 ft) in diameter, and some 170 m deep (570 ft). It is surrounded by a 45 m (150 ft) high rim of rock, raised above the surrounding plains by the force of the impact. The bottom of the crater is filled with rubble from the impact, to a depth of 213-244 m (700-800 ft) below the crater's center.
