Hitchhiker's Guide to Rukl Chart 1

Oenopides (Robin Casady)

Oenopides showed sections of its far rim hovering in the shadow.

Markov (...Akkana)

Rukl's drawing of Markov looks interesting, as though it has concentric rings inside it. An inner ring from the impact which created it? Concentric rilles, like we see on some of the maria? Please send in your observations!
