Crustal Blocks in the Walls of Coprates Chasma
ESP_080616_1640 Science Theme: Composition and Photometry

The deep canyon walls of Valles Marineris might expose ancient crustal materials. Blocks of bedrock with diverse colors are visible in the enhanced-color cutout. These large, jumbled blocks might have resulted from heavy bombardment by asteroids about 3.9 billion years ago.
