Hydraotes Chaos

This VIS image shows part of Hydraotes Chaos. 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. Hydraotes Chaos measures about 300 kilometers (190 miles) wide by roughly 350 km (220 mi) north-south, and it lies in a valley leading northeast out of Ganges Chasma at the east end of Valles Marineris. Tiu Valles flows northward from Hydraotes Chaos to empty into Chryse Planitia.
