Sirenum Fossae is a long trough in several quadrangles including Memnonia quadrangle and Phaethontis quadrangle of Mars, centered at 35.57° south latitude and 197.26° west longitude.[1] Sirenum Fossae is 2,735 km long and was named after a classical albedo feature name.[2] Troughs on Mars like this one are called Fossae. Sirenum Fossae is believed to have formed by movement along a pair of faults causing a center section to drop down. This kind of feature is called a graben.
