Kalkkop Crater in Blue Crane Route Rural, Eastern Cape
The Kalkkop Crater is situated near Kendrew, about 50 km south of Graaff-Reinet in the Eastern Cape, South Africa.
This is the third known crater in South Africa and can be found on private farmlands that are accessible via a dirt road without obtaining permission. The crater was created when a 20 meter wide meteorite crashed into earth approximately 250 000 years ago. The meteorite left a crater about 90 meters deep and 640 meters wide. It bears resemblance to the famous Meteor Crater of Arizona or Tswaing north of Pretoria, but only about half as big. The estimated date of the impact was determined after a borehole was sunk into the core of the Crater. The drilling took place between 1992 and 1994.
After time a shallow pool of water developed at the bottom and after evaporation a limestone layer was all that was left. After many years of this process taking place again and again and the Karoo becoming drier, erosion occurred leaving just the circular impact ridge of the crater visible today.
