It lies along the northeastern outer rim of the huge walled plain Hertzsprung, and to the southwest of the crater Kolhörster.

This is a heavily eroded crater formation with multiple impacts along the rim edge and within the interior.

There are small craters across the interior floor, including impacts along the north, west and southeastern edges.

This feature is radial to the Mare Orientale impact basin, and passes near the outer rim of the crater Grachev.

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