What we see on the Chart: Coming in from the north the edge of Mare Tranquillitatis, and the low rille Rime Hypatia. The grand carters Theophilus Cyrillus and Catharina ( Chart 57) together form a prominent group. Craters Kant B, and Zöllner E on the other side of the high plain are covered with lava, and the mountain massif north-east of Kant gets as high as 4000m.
