Mons Gruithuisen -
Moon age 11.5 days (83 %)
The Gruithuisen domes Gamma and Delta
are located north of the crater Gruithuisen (19 km). They are large and
probably intrusive structures.
They are the highest
volcanic structures. Gruithuisen Gamma has a diameter of 19 km and reaches a
height of 1 750 meters above the surrounding level. Gruithuisen Delta is with
27 km significantly larger and reaches a height of 1 900
meters.
Both structures are so large that the Celestron
14 shows some structures on both domes. In the image also visible is the Rima
Deslisle, which is just 500 meters wide at its narrowest point. |

Putative domes north of Tobias
Mayer - Moon age
10.6 days (74 %)
The next three
images show the putative volcanic plateaus north of Tobias Mayer near the dome
fields of Milichius and Hortensius.
The eastern plateaus show
an intrusive structure with rilles that western rather an effusive structure
with an elongated summit vent. |
