It is not the clearest of lunar craters, its ringed plain defined by a gently raised rim to the west, appearing broken in form to the east. It forms a characteristic trio with 60km Bonpland and 48km Parry to the south. This pair are ancient too, but presumably younger than Fra Mauro as their rims appear to bulge into Fra Mauro's boundary, inverting the curve of the walled plain's rim. This suggests they were formed after Fra Mauro and overlay its edge.
