− | <p>At 225 km wide and nearly 5 km deep, Clavius dominates the southern highlands when the illumination is low, but near full Moon it nearly [http://www.lpod.org/?m=20061119 disappears]. In between these extremes Clavius is wide open, its floor fully exposed, with just enough shadowing to highlight scarps. Damian’s gorgeous shot shows a smooth floor with a few stubby central peaks. The floor is generally thought to be fluidized ejecta from Orientale or Imbrium; it could be lava flows, but certainly not dark ones like mare basalts. The youngest, somewhat large crater - Rutherfurd (54 km, bottom-center on Clavius’ rim) - has totally slumped walls and possible patches of impact melt on its floor. Ejecta from Rutherfurd radiates away in a few lines of just resolved secondary crater pits. A nice Christmas present.</p> | + | <p>At 225 km wide and nearly 5 km deep, Clavius dominates the southern highlands when the illumination is low, but near full Moon it nearly [[November_19,_2006|disappears]].
