The collision that created Hargraves Crater impacted into diverse bedrock lithologies of ancient Mars. As a result, the impact ejecta is a rich mix of rock types with different colors and textures.

The crater is named after Robert Hargraves who discovered and studied meteorite impacts on the Earth.
