Nestled in Ghana’s Ashanti gold belt is the Bosumtwi crater, a geological and cultural gem formed over a million years ago by a meteorite impact. It remains one of the world’s best-preserved impact sites and is sacred to the Ashanti people. While most impact craters are buried under sediments accumulated over millennia, the Bosumtwi crater remains exposed and is filled by a lake. Given how well-preserved the site is, a rarity, it is also scientifically invaluable. However, recent studies reveal that illegal artisanal mining is rapidly degrading the crater’s rim and threatening the lake’s ecosystem with toxic runoff. Beyond damaging a vital natural laboratory for studying planetary history, this destruction risks erasing centuries of cultural heritage. Consequently, experts advocate for the site’s protection, using methods such as satellite surveillance, stricter enforcement, and community engagement.
