Acraman crater, Impact crater in Gawler Ranges, Australia.
Acraman crater is a circular impact structure in the Gawler Ranges marked by a lake at its center. The structure measures about 20 kilometers across and sits in a remote, sparsely populated region of South Australia.
The crater formed about 590 million years ago when a large asteroid struck Earth during the Ediacaran period. This impact is among the oldest known impact craters on the continent.
The crater and surrounding area take their name from John Acraman, a prominent colonial businessman in South Australia. His name marks his connection to the region's past.
The site is very remote and requires four-wheel-drive vehicles to reach it. The area has few facilities, so prepare beforehand for local conditions.
The impact ejected material far across the landscape, settling into marine sediments roughly 300 kilometers away in the Flinders Ranges. This spread shows the force of the collision and its effects over a vast region.

Meteorite craters mark locations where asteroids collided with Earth. These geological structures range from 110 meters to 300 kilometers in diameter. They often contain distinct minerals like diamonds, nickel, and copper. Scientists use the craters to study Earth's history and cosmic events.
