Look carefully at the inner walls of Aristarchus. Notice anything unusual? Not the bright spot on the near rim which is where a ray was deposited. Look at the opposite rim where a terrace near the top of the rim bends sharply down and about halfway down the rim turns up and stops. The terrace directly below it repeats the Z shape. Terraces don't do this. They are places where a large, fairly coherent mass of rim material slides downslope as a unit. Often terraces can be traced halfway or sometimes nearly all the way around the rim, showing that the whole annular block slid down at the same time - what a sight! The Zs show up in Alan Friedman's [[November_12,_2007|shot]] has a high opposite lighting, clearly revealing the wall, but the Zs are not apparent. No better luck with Clementine, nor Apollo. Although it looks real I am beginning to think the Zs are a trick of lighting, rather than bending terraces. Who can come up with images to resolve this uncertainty?<br /><br />
