Unless stated otherwise, all photographs will be oriented such that north is up and lunar west to the left.
|17||Schroter's Valley||Giant sinuous rille||26.2°N||50.8°W||168 km||Rükl 18|
|22||Aristarchus Plateau||Mysterious uplifted region mantled with pyroclastics||26.0°N||51.0°W||150 km||Rükl 18|
The crater with the bright wall, its most easily observed feature, is Aristarchus (L11). The wall is actually distinctly terraced but the terracing is not evident in this photo. The highlands to the northwest is the Aristarchus plateau (L22). The plateau is a little more prominent in the Gruithuisen domes photo. West of Aristarchus and the Aristarchus plateau is Schroter's Valley (L17), a gigantic rille which was quite obvious this evening. To the east are the Montes Harbinger and to the northeast, the Gruithuisen domes and their associated lava field.
|42||Marius Hills||Complex of volcanic domes and hills||12.5°N||54.0°W||125 km||Rükl 28,29|
The crater near the center of the photo is Marius. Scattered all around to the west are the Marius Hills. With the right light and good seeing, what a surprise.
|62||Rümker Hills||Large volcanic dome||40.8°N||58.1°W||70 km||Rükl 8|
Photographing the Rümker Hills is as much an issue of timing, to get the favorable shadows, as it is skill. Under this light, this turned out to be an interesting region. Note Mons Rümker to the south and the other domes in the region.
|91||De Gasparis Rilles||Area with many rilles||25.9°S||50.7°W||30 km||Rükl 51|
The larger crater with central peaks to the northeast is Gassendi (L13). The fractured floor of this crater is not clearly visible in this photo with this sun angle but some lighter "lines", sunlight reflected off some fractures are visible giving hints of this structure. The flat region below and to the east is Mare Humorum.
The crater with the domed floor to the southwest of the photo is Mersenius (L44) which has the "micro" craters. Three or four of these micro craters are just visible in this image.
Finally, note the linear depressions or channels to the southwest. This is the de Gasparis Rille region (L91). It looks like one can trace these past the east side of Mersenius up to the west side of Gassendi.
|94||Drygalski||Large south-pole region crater||79.3°S||84.9°W||149 km||Rükl 72,VI|
Drygalski is visible because of libration. The Leibnitz Mountains appear to the right.
