| − | <p>The NE limb, between maria Marginis and Humboldtianum, is marked by one large crater. Gauss is 177 km wide and of unknown depth - until someone measures shadow lengths on Stefan’s lovely low Sun image. Lunar Orbiter [http://www.lpod.org/?m=20060216 images] reveal Gauss to be a floor-fractured crater (ffc), with rilles along the eastern, northern and western walls and down the middle of the floor. These rilles are essentially invisible from Earth, but are hinted at in these views. The bottom image also suggests that the eastern portion of Gauss’ floor may be somewhat domed - at least enough to cast a linear shadow. Doming and rilles are two common characteristics of ffc, and a third is pyroclastic deposits, which Clementine high Sun images show are there too. Amazing as it may be, there is a feature here even more interesting than Gauss. Check tomorrow’s LPOD to find out what it is - or do you see the subtle hint of it?</p> | + | <p>The NE limb, between maria Marginis and Humboldtianum, is marked by one large crater.
