This survey of the canyon ground of Tithonium Chasma in Valles Marineris reveals terrain of two distinct ages. The slopes and hilltops right here are made up of tough rocky outcrop that was sculpted by influence craters of all sizes. In distinction, the valley flooring are crammed with gentle toned, clean supplies with far fewer giant craters.
At HiRISE decision, we will see that the “clean” supplies are in reality plagued by boulders and small influence craters, so they can’t have been emplaced very not too long ago. Nonetheless, the absence of bigger craters tells us that the sleek supplies are a lot youthful than the traditional rocky outcrops of the canyon ground.
The sleek supplies look like sediments that had been deposited presumably by the wind, lengthy after the canyon was shaped. The sediments crammed within the low mendacity spots within the canyon ground, leaving a panorama that resembles lakes and ponds however is made up of mud and sand as a substitute of water.
The map is projected right here at a scale of fifty centimeters (19.7 inches) per pixel. (The unique picture scale is 53.5 centimeters [21.1 inches] per pixel [with 2 x 2 binning]; objects on the order of 160 centimeters [63.0 inches] throughout are resolved.) North is up.
