Chryse Chaos

This VIS image shows part of Chryse Chaos (bottom of image) near the terminal end of the huge outflow channels draining from Valles Marineris into Chyrse Planitia. Chaos terrain is typified by regions of blocky, often steep sided, mesas interspersed with deep valleys. With time and erosion the valleys widen and the mesas become smaller. It has been proposed that a catastrophic outflow of subsurface water creates the chaos and provides the surface flow creating the channel. Chaos terrain is also found along the course of most of channels in this region and may occur where the channel flow fluid warms the subsurface ice creating additional release points for melted subsurface ice. The chaos terrain in this image still retain the classic steep sided large mesas. The top of the image shows one of the many channel segments that make up Tiu Valles. Tiu Vallis is 1720 km (1069 miles) long.
