A Giant Hidden Hole?
image by Damian Peach
A more unexpected discovery is that the floor of Pitatus is no where near flat. The right profile is a traverse from north to south to the right of the central peak. The floor rises from the northern trough to a rounded flatness and then dives down into a wide depression the occupies the entire south half of the crater floor. If you look at Damian's image you'll notice a faint NW-SE diagonal rille - that is where the depression starts, a hinge line. The hole is about 50 km wide and 400 m deep. Profiles in other directions confirm this monster feature, and yet there is no visual sign of it. Does it show up in very low Sun views? Is it real or a defect of the LRO topo? Strange.
