Vernal is a
crater
A crater is a landform consisting of a hole or depression (geology), depression on a planetary surface, usually caused either by an object hitting the surface, or by geological activity on the planet. A crater has classically been described ...

Springs
A study of images taken with the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter suggests that hot springs once existed in Vernal crater, in the Oxia Palus quadrangle. These springs may have provided a long-time location for life. Furthermore, mineral deposits associated with these springs may have preserved traces of Martian life. In Vernal Crater, on a dark part of the floor two light-toned, elliptical structures closely resemble hot springs on the Earth. They have inner and outer halos, with roughly circular depressions. Many hills are lined up close to the springs. These are thought to have formed by the movement of fluids along the boundaries of dipping beds. The discovery of opaline silica by the Mars Rovers on the surface also suggests the presence of hot springs. Scientists proposed this area as one to be visited by the
