A Wondrous Image!

A Wondrous Image! Like a comet, the Oppel Ridge widens and becomes less conspicuous where it streaks away from a small nameless crater along the northern shore of Mare Crisium. Oppel is part of the circular mare ridge system that defines a 375 km wide inner ring of the Crisium basin, but its character seems different than the other ridges. In this marvelous low sun view it appears superimposed upon the topography. Its edges are partially marked by ridges and the center part is like a raised welt its elevation is emphasized by its brightness as the surrounding maria darkens as the terminator is approached. The low sun also brings out a feature Ive never noticed before a slot-like depression north of the Oppel Ridge. The best Lunar Orbiter 4 view shows this only as a low area bounded by two ridges, but it is obviously an undiscovered graben. Where the graben reaches the basin shore, Crisiums normal blocky mountains (massifs) appear rounded and dome-like, and both of these rounded hills has a summit pit. I dont think these hills are volcanoes (although they do look something like the Gruithuisen volcanic domes ), but they are surprising. Wow! Every great image like this teaches me more about the Moon! I want to learn more so I encourage everyone to take more low sun images of insufficiently explored regions like this!
