I often focus the picture in a single crater, but there are places with such interesting lunar resources that we cover in one context a large area like a bowl, or simply in a single lunar corner. In this particular photo we have of these regional scenes that concatenates a variety of landforms in a nice display. This image, which stretches from Atlas and Hercules in the foreground, through Endymion to the mare humboldtianum is one of the most beautiful corners of the Moon.

Atlas is a fractured crater floor with rhymes and dark pyroclastic deposits, as Endymion is a large, crater Plato in style with a smooth and darker floor. But what really draws attention in this picture is the clarity of detail that was captured mare humboldtianum, it is easy to see the chain of mountains located on the inner edge of the other side, since the side facing the Earth is more difficult to detect as it is indistinct due to lack of contrast with the remainder of the relief.

Located along the northeastern limb of the Moon (centered at about 56.8 N, 81.5 E), Humboldtianum Basin is a region of interest to NASA. The data show that the basin 650 kilometers in diameter is about 4.5 km deep. The Basin Humboldtianum would have been formed during the Moon Nectarian period, roughly between 3.92 to 3.85 billion years ago. Many other multi-ring impact basins appear to have formed during this time period, including the bowl Crisium.

The inner ring of Humboldtianum Basin have the mare humboldtianum (Humboldt Sea), and data from probes reveal that he has a relatively smooth and younger floor as the rest of the basin, probably formed during the period between 3.8 to 3 Imbrian 6 billion years ago.

Mare humboldtianum (273 km in diameter) is an ancient impact basin, whose inner ring was flooded by basalt being a difficult viewing area for placing on the libration zone.

Mare humboldtianum was named after the explorer Alexander von Humboldt (1769-1859) and is one of only two lunar seas with the names of people, the other mare smythii given in honor of the British astronomer William Henry Smyth (1788-1865).

What makes this picture so wonderful is the absolute sharpness throughout the field of view is not always easy to get such a good definition without resorting to mosaic.!
