Believed to have started as a crack as the planet was cooling, the massive gash in the surface is 600 kilometers across at its widest point, and stretches 8 kilometers deep. The earth's grand canyon is less than a third of its length, only 1.8 kilometers deep, and a 20th of its girth. to peer down a chasm so deep would certainly be intimidating. This mosaic was build from images taken in the 70 by the viking orbiter.
