Both are complex craters with a central ring of islands visible in Clearwater West. Below the water line Clearwater East has a pronounced central uplift that has been obscured by sedimentation and glacial erosion. The impact origin of these craters was confirmed when maskelynite (glass formed from a shock wave traveling through plagioclase minerals in gabbroic rocks) was found, along with fine shattering and intense fracturing of the target rocks. The age of both craters is 290 million years.
