It has lots of fine, talcum-powderlike dust mixed with a complete variety of pebbles, rocks, and boulders. Many pebbles, fewer rocks, and even fewer boulders naturally make up its surface. The dust is a very fine, overall dark gray. And with no air molecules to separate the dust, it clings together like cement.
