Context image This VIS image shows part of Gorgonum 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. Chaotic regions form when groundwater escapes to the surface, undermining it and causing the ground to

Context image Today’s VIS image shows a portion of Sirenum Fossae. The linear features are tectonic graben. Graben are formed by extension of the crust and faulting. When large amounts of pressure or tension are applied to rocks on timescales that are fast enough that the rock cannot respond by deforming, the rock breaks

Context image Today’s VIS image shows the complete length of two channels in northern Terra Sirenum. As with all channels in this region – including Mangala Valles – the flow is northward into the low elevation region south of Amazonis Mensa. Abus Vallis is on the left and is 66 km long (41 miles).
