Yerkes 1 at the western edge of
Mare Crisium Yerkes 1 is located on the western edge of Mare Crisium, in the south-eastward direction of a small ridge. In the Consolidated Lunar Dome Catalogue of the Geological Lunar Researches Group (GLR) it is catalogued as an effusive lunar dome with a diameter of about 9.5 km and a height of about 110 m. It is located at 49.96° East and 14.82° North. The small crater near Yerkes 1 has a diameter of about 3 km and is strong distorted in north-south direction due to its location next to the lunar limb. Its surface is crossed by several rilles whose origin lies further north. The 31 km wide crater Lick can be found in the southeast of Yerkes 1. It is a typical example of a Floor Fractured crater, with a lunar dome on the crater floor. |

Looking at the LRO image of Ye 1 a further upwarp (A), associated
with rilles, can be seen to the west (left). To the east (B) and south (C) are
also two smaller domes with summit calderas. < LRO image of Ye 1 and its surroundings with the labeled structures A, B and C. The image has a resolution of 125 meters/pixel and shows the area in equidistant cylindrical projection. Under a purely morphological view in combination with the intersecting rilles system one would consider Ye 1 Ye 1 rather as an intrusvive structure than an effusive Dome. But remember that the high resolution lunar images were not available at the time when the Consolidated Lunar Dome catalogue was published. |

Lick and Taruntius Both craters are typical examples of so-called Floor Fractured crater. Taruntius (56 km) is located on the northeastern edge of Mare Fecunditatis and shows an annular fracture zone. At full moon two areas with pyroclastic deposits become visible. Lick (31 km ) is located on the southwestern edge of Mare Crisium and shows a classic intrusive upwarp of the crater floor with resulting rupture zones. In the middle of the crater, the crater floor bulges up to an altitude of 300 m. A special feature of Lick is the small lunar Cone with its caldera on the western crater wall.

< High resolution LRO images of Taruntius and Lick in
equidistant cylindrical projection with a resolution of 125 m/px. A small, symmetrical lunar dome with a summit caldera is located at the western crater wall of Lick. It is one of the few calderas on the crater floor. The structure has a diameter of about 2 km at the base. The large LRO image from Lick shows the Dome as Inlet with a resolution of 64 m/px. Click here for a height profile of Lick in east-west direction with clearly shows the central upwarp. |

NEW 2016 Lick This image was taken in june 2016 at a moon age of just 3.3 days (illumination 12.3%). The image quality is not very good, we have add it, because it show clearly the upwarding of the crater floor. |
 |
NEW 2016 Yerkes 1 at the western egde of
Mare Crisium The complex Ye 1 is still visible at this illumination. This recording is just a supplement because it does not reach the quality of the other images. |
 |
Yerkes 1 on the western egde of
Mare Crisium The shallower part of Ye 1 is practically invisible at an illumination of 21 %. Only the upper part remains still clearly detectable. The small lunar Cone in the ecrater Lick is still visible in this image. |
 |
Cauchy Domefield From an illumination of about 20 % the large dome field in the west of crater Cauchy becomes visible. The two major effusive domes Cauchy Omega (with summit caldera) and Cauchy Tau are visible at the terminator. The Cauchy region is an interesting area and includes 20 domes as well as Rupa and Rimes Cauchy. A detailed description can be found in segment 05 A. LRO image with a resolution of 125 m/px of the domes Cauchy Omega and Tau. |
 |
Gardner Megadomeplateau Also from an illumination of about 21 % the putative megadomeplateau Garner is visible. The size in east-west direction is about 70 kilometers. Further images can be found in segment 5 A. LRO image of the Gardner plateau with a resolution of 500 m/px. |
