THEMIS: Chaos in Morava Valles

Morava Valles (THEMIS_IOTD_20190905)THEMIS Image of the Day, September 5, 2019. Located in Margaritifer Terra, Morava Valles is one of several channels that empty northward towards Chryse 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.

Morava Valles arises from a region of chaos. Chaos terrain is also found along the course of the channel and may occur when the channel flow fluid warms the subsurface ice creating additional release points for melted subsurface ice. This VIS image shows a region of chaos near the terminal end of Morava Valles.
