Edge World

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?

(1) In answer to the first question: it lacks the clarity of Jérôme's photo, but the shadow cast by the scarp in Hayn A at a lower sun angle is visible in Plate A1 of the Consolidated Lunar Atlas. - JimMosher
