ANOTHER CORNER
image by Rafael Benavides, Posadas, Córdoba, Spain
Rafael has had fabulous luck with Humorum. He has captured excellent images of the [/LPOD%20Feb%207%2C%202008 southeast] and [/LPOD%20Feb%208%2C%202008 southwest] corners of the basin, and now the northwest. His images are low Sun closeups of the region between the maria and outer basin rings. This is typically a swampy area where ejecta, mountain rings and localized puddles of mare lava intermix. And that is what is here, with a variety of rilles, mostly heading northwards. There are also some domes. The biggest definite dome is on the floor of Mersenius P, indicated by its slightly bright sun-facing slope matched with a slightly dusky shadowed side. A somewhat smaller dome (arrow) occurs to the north on the lava-covered floor of a possible ruined crater. Although these two domes look very similar a glance at the Clementine UVVIS multi-spectral mosaic shows that the smaller dome formed on dark mare material, but the one in P is on mare-looking stuff that is covered with bright ejecta - it is probably the older of the two domes. A third, possible larger dome is hinted at on the floor of Mersenius, just above the "M". This one occurs where there are many thin rilles and the Clementine image shows a volcanic dark halo at about the same spot. Is it a real dome?
