Hipparchus, +085,-090: One of the largest ring formations on the entire lunar surface, but is rarely seen as connected whole save under low illumination. One hundred miles across, the great mountain-ringed enclose is in a ruinous condition and the walls are very broken and disconnected, consisting of mountain passes separated by valleys, on a smaller scale but similar to the southern coastline of Mare Crisium (Wilkins and Moore, The Moon, Faber & Faber, 1955)
