What is "haldane"

Haldane is a lunar crater that is located in Mare Smythii, near the eastern limb of the Moon. The visibility of this formation is affected by libration, and even under favorable conditions it is highly foreshortened. It lies just to the west-northwest of the crater Runge, and to the east of Carrillo.

The interior of this floor has been flooded by lava, leaving only a low rim projecting up through the lunar mare. This rim is broken along the northwest face, leaving a gap into the interior. In the eastern half of the inner floor is a semi-circular feature that is concentric with the outer wall. There is also a low central ridge offset to the east of the interior midpoint.

Haldane is a somewhat extreme example of many fracture-floored craters in Mare Smythii.
