Prinz,Kreiger, Harbinger Mountain Region

The kilometer high rim of Prinz (47 km.) crater was casting a shadow across its own lava flooded floor. The uplifted Harbinger mountains were also casting fine shadows in this region with its large magma ponds pushing up and freezing in the distant past. The uplifting doming in the region created many fissures for lava escape and flooding to occur. Several fissures could be seen clearly on this night of steady seeing conditions. From the crater Krieger (22 km.) north and somewhat east of Aristarchus (not in this sketch) four distinct long shadows could be seen crossing the edge of the Aristarchus plateau where the terminator was located during the rendering of this sketch. In addition to these features the following are included in the sketch: Angstrom (9.8 km.), Wollaston (10 km.), Artsimovich (9 km.), Van Biesbroeck (10 km.), Dorsa Argand and the Prinz rilles.

Sketching was somewhat challenging for me without my drive platform for the scope.
