Moreux Crater is a crater in the Ismenius Lacus quadrangle

Ismenius Lacus quadrangle

The Ismenius Lacus quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey Astrogeology Research Program. The quadrangle is located in the northwestern portion of Mars’ eastern hemisphere and covers 0° to 60° east longitude and 30° to 65° north...

Glaciers

Moreux Crater's appearance has been shaped by the action of glaciers. Glaciers modified large areas of the surface of Mars. Many places are believed to still contain enormous amounts of water ice that was associated with glaciers. Glaciers have shaped much of the fretted terrain. It would be difficult to take a hike on the fretted terrain because the surface is folded, pitted, and often covered with linear striations. The striations show the direction of movement. Much of this rough texture is due to sublimation of buried ice. When the ice transitions directly into a gas it leaves behind an empty space. Overlying material then collapses into the void. Glaciers are not pure ice; they contain dirt and rocks. At times, they will dump their load of materials into ridges. Such ridges are called moraines. Some places on Mars have groups of ridges that are twisted around; this may have been due to more movement after the ridges were put into place. Sometimes chunks of ice fall from the glacier and get buried in the land surface. When they melt and more or less round hole remains. On Earth we call these features kettles or kettle holes.
