Elysium Fossae
The Elysium Fossae are a group of large troughs in the Elysium quadrangle of Mars at 24.8° north latitude and 213.7° west longitude. They are about 1,175 km long and are named after a classical albedo feature name.
Troughs.
Large troughs (long narrow depressions) are called fossae in the geographical language used for Mars. Troughs are created when the crust is stretched until it breaks. The stretching can be due to the large weight of a nearby volcano. Fossae/pit craters are common
of the debouchment of Athabasca Valles and has been dated by crater counting to be the oldest extant geologic unit in the Athabasca Valles system, and is Noachian in age. Modern extensional near-source faulting associated with southern Cerberus Fossae has been found to postdate the formation of all features in the valley, and are likely the most geologically recent features of the Athabasca Valles system.
Athabasca Valles is located within the broader Elysium Planitia region and cross-cuts a vast swath of plains land interpreted to be composed largely of flood basalts
