At its north end of the ridge (Fig 78) becomes a scarp that wraps around the base of the highlands like a shoved rug. Were the mare lavas thrust against the highlands? This might seem easiest to imagine if the lavas had been only partly solidified when they were deformed, but the lavas had had plenty of time to solidify. The ridge deforms numerous impact craters, such as the one near the bottom of the photograph. A long time - probably hundreds of millions of years - had to pass for these impact craters to form after the lavas crusted over and before the ridge formed. - K.A.H
