Two hundred or so kilometers to the southwest of the Altai Scarp you will find a mix of large and small highland craters that may catch your eye as they did mine. Many have written of the “boring” look-a-like craters of this region but good lighting can make a big difference in appeal here. Ancient Riccius crater (71 km.) is a worn, an almost obliterated remnant, covered and surrounded by crater from 10-15 km. of various ages. Adjacent to Riccius is crater Rabbi Levi (81 km.) with an interesting short chain of craters across its floor. The next crater Zagut (84 km.) is the largest of those in the sketch with Zagut A (11 km.) near the center of the floor and Zagut E (35 km.) pushed through the eastern wall of Zagut. Next to Zagut is crater Lindenau (53 km.) which is younger than the other large crater here as evidenced by the sharper rim and what looks like a part of a central peak remaining.

  3. Hi Frank,

    impressive sketch! Simply wonderful!
    BTW: Quite funny: I live in a German village called Lindenau… 🙂

    Best,

  4. Christian,

    Thank you.

    I’m certain the Lindenau of Germany is a much nicer place to live than the Lunar Lindenau.

    Frank 🙂
