**Hydraotes Chaos** is a broken-up region in the [Oxia Palus quadrangle](/source/Oxia_Palus_quadrangle) of [Mars](/source/Mars), located at 0.8° North and 35.4° West. It is 417.5 km across and was named after a classical [albedo](/source/Albedo) feature name.[1] More information and more examples of chaos regions can be found at [Martian chaos terrain](/source/Martian_chaos_terrain). The area contains small conical edifices, called [Hydraotes Colles](https://en.wikipedia.org/w/index.php?title=Hydraotes_Colles&action=edit&redlink=1),[2] which were interpreted as the Martian equivalent of terrestrial [cinder cones](/source/Cinder_cone) formed by [volcanic activity](/source/Volcanism).[3]
