Little but Good

Lacus Bonitatis is a place few of us have noticed. It is the only named one of the small leakages of mare lava inside
the Geminus scarp ring of the Crisium Basin. In looking at Dmitry's waxing Moon mosaic I was impressed with what I
could distinguish with this full Moon lighting. For example, the dark halo craters within Cleomedes are better seen than
on the same scale LRO mosaic. Another feature in the high Sun view that attracted my interest is the thin strip of mare
with two or three fingers extending southward. This is a slightly darker lava, either younger or a different composition
than others nearby. We need more high resolution images like Dmitry's to explore albedo variations and the reasons for
them.
