erupting from localized vents followed by relatively slow cooling. Mons Rümker is surrounded by a scarp that separates it from the adjacent mare. The plateau rises to an altitude of 900 m in the west, 1,100 m in the south and 650 m in the east. The surface of Mons Rümker is relatively uniform, with a strong spectroscopic signature of lunar mare material. The estimated volume of lava extruded to create this feature is 1,800 km3. A young lava plain to the northeast from Mons Rümker, named Statio Tianchuan, was the landing site of the
