Not the Mare
image by Stefan Buda, Melbourne Australia
I like Humboldt, the crater, because it is so hard to see but is so interesting. Stefan has captured it with low lighting that emphasizes the central range of peaks and the suggestion of a domed floor. Meuarements with the QuickMap Path tool show that the center of the floor - not the peaks - is up to 600 m higher than the edges. Some of the radial and concentric rilles are visible, as is the southwestern patch of mare lava. Tomorrow will be another, previously unseen view of this complex floor-fractured crater.
