Lake Bosumtwi - Impact Crater

Impact Crater

The Lake Bosumtwi impact crater is 10.5 km in diameter, slightly larger than the present lake, and is estimated to be 1.07 million years old (Pleistocene period).

The crater has been partly eroded, and is situated in dense rainforest, making it difficult to study and confirm its origin by meteorite impact. Shock features such as shatter cones are largely overgrown by vegetation or covered by the lake. However, drilling of the crater's central uplift beneath the lake floor has recently provided an abundance of shocked materials for scientific study. Tektites, believed to be from this impact, are found in the neighbouring country of Ivory Coast, and related microtektites have been found in deep sea sediments west of the African continent.
