The Planetary Report
Mars—A Soviet Destination On the Cover: Valles Marineris, the Red Planet's "Grand Canyon, " stretches one-fifth of the way around Mars. Within its walls lie records of the planet's geologic past. This computer-constructed mosaic of Viking images shows a portion of Candor Chasma, a small section of the larger canyon complex. In the region shown, the canyon is about 9 kilometers deep and 100 kilometers wide. Its floor is covered with landslide debris and layered deposits, perhaps the remains of an ancient lake.
