The central peaks of 198 km wide Belkovich are right on the 90°E meridian, and here we can see a little beyond to the far rim of the giant crater. Belkovich A is a broad, smooth-floored crater with the simple crater B inside it. Hayn is a fresh crater with central peaks. Here you can see a characteristic of peaks - they are much lower (almost always) than the walls of their craters. The crater Hayn A is unusual for having a curved Humboldtianum Basin?
