Hitchhiker's Guide to Rukl Chart 9

Mons Gruithuisen (David North <d _at_ timocharis.com>)
The mons Gruithuisen, Gamma and Delta, are occasionally gifted with a light angle that brings out maximal contrast. Gamma's central crater shows very well. I must admit some frustration with Delta, though. Quite a bit of detail is visible, but I'm uncertain of any peak crater. At times, maybe a hint. I have thought I spied it in the past, but it has been a while, and doubts creep in...

[ ... ] we made a half-hearted attempt at the central craters of Mons Gruithuisen Gamma and Delta, but the sky would not support that kind of tight look. It seemed a good time to give it the old college try, though, since they were just emerging into day.

Mairan (Matt Tarlach <tarlach _at_ earthlink.net>)
Moving south along the terminator, the highlands around Mairan showed some nice mottling, which appears on the map as hundreds of small craters. The nearby Mons Gruithuisen struck me as smooth and "soft" by comparison, reminiscent of volcanic cinder cones. Rima Sharp also showed nicely right by the terminator.
