CAW Note: There aren't many ways to elevate a crater rim once it is formed, but gravity pulls rim segments down, producing slumps and terraces. So another way the east wall and mega-terrace could be reconstructed would be to move the terrace block upward and eastward to where it may have come from. Posidonius formed on the edge of an impact basin so tilted inward from the beginning.
