Langrenus (80 miles) is a great crater. The walls are terraced and I can see three separate layers of terracing. The walls are probably 2 or more miles high. There is a very nice central mountain mass composed of at least two main peaks. My personal estimation of their height is about 1 mile high. This is a showcase formation at any star party. Observe it 3 days after new Moon.

Barkla (26 miles) is a deep crater to the east of Langrenus. It is less than 2 miles deep. It has a nice central mountain that is under a mile high.
