The meteorite impacted about 50,000 years ago, during the Pleistocene Epoch, and at that time the area was grassland and wood, and inhabited by mammoths and giant sloths. This punched a deep hole through the sediment and into the granite forming the continental shelf, fracturing the rock to a depth of 5 miles (8 km).
