About this work
Large craters, like this 50-kilometer diameter one, can uplift material from below and form a mountain-like central peak. Craters of this size on Mars become unstable as they form and collapse due to gravity. Craters with central peaks and terraced rims are referred to as "complex" craters. Geologists study these central peaks because the uplifted bedrock was once deep within the Martian crust.
