It is located next to the linear valley named Vallis Rheita, in the rugged southeastern quadrant.

To the northwest along the same valley formation is the crater Young.

The satellite crater Mallet A lies across the southwest part of the interior floor, and encroaches along the southwestern inner wall.

The remaining interior floor is marked by a small craterlet near the northern inner wall.

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