[1] The northern part of the rim is completely missing, and opens into the Oceanus Procellarum, forming a bay along the southwestern shore.

The rim is the most intact along the eastern stretch, forming a mountainous promontory into the mare.

The wrinkle ridge Dorsa Rubey traverses the floor from north to south,[2] and outlines a portion of the missing rim.

The crater floor is otherwise nearly smooth and relatively free of craterlets, with the exception of Letronne B near the southeast rim.

[3] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Letronne.
