Lake Bosumtwi, Ghana's Sacred Impact Crater, Sees Surge in Gold Mining Activity
“The image reveals exposed veins of gold around the lake, a result of mineral-rich magma rising to the surface after the impact.”
A satellite image from Landsat 8, captured on December 29, 2015, documents a striking view of Lake Bosumtwi in Ghana. This natural lake was formed roughly 1 million years ago by a massive asteroid impact.
The 2015 image clearly shows exposed veins of gold ringing the lake. These deposits are a direct geological consequence of the ancient impact, which caused mineral-rich magma to rise to the surface. The site remains sacred to the Asante people.
A Changing Landscape
Recent comparison with a satellite image from 2024 reveals a significant transformation in the region. Gold mining activity has increased markedly around the lake's perimeter.
The most visible change, however, is the lake itself. In the newer image, Lake Bosumtwi appears green—a dramatic shift caused by higher concentrations of phytoplankton in the water, likely linked to increased nutrient runoff from nearby mining operations.
