Pallas and Murchison (50 and 58 km) are two craters separated by a straight interrupted wall. I can not figure out what caused this wall. At first glance you would say it is the rim of these craters, but it intrigues me that the wall extends at both ends, not being rounded. Is it possible that Pallas and Murchison have formed simultaneously from two impacts of two bodies that collided with the Moon, coming from opposite sides?
Pallas and Murchison communicate with each other through an opening in the wall. Murchison's rim, is at south-east "eated", making an exit to the Sinus Medii area, which is at the south.
