eponym=Johann von Lamont Lamont is a low ridge in the surface of
Mare Tranquillitatis that is most likely an impact feature. It is located to the southeast of Arago crater.Lamont has the shape of two roughly concentric but incomplete rings with an inner diameter of 60 km and an outer diameter of 120 km. (The official diameter is 75 km.) Radial ridges radiate away from the center of Lamont, except in the east and west quadrants. The ridge system is only a few hundred meters in height, with a width that averages 5 km but is thicker to the southeast. This feature is only readily visible at low angles of illumination, when shadows highlight the terrain features.
This feature is associated with a mass concentration (
mascon ); a sub-surface region of higher-density material.References
