Phlegra Montes

The Phlegra Montes are a system of mountains in the Cebrenia quadrangle of Mars, located at 40.4 degrees north latitude and 163.71 degrees east longitude. They are 1,350 km across and were named after a classical albedo feature name. They form a complex system of isolated hills, ridges and small basins, and it was suggested they have endogenic tectonic origin.
