Hi, Ed– When I see an anticline that has eroded to a pair of ridges, I speculate that either (a) the ridges represent the most erosion-resistant layers (thus the center is more eroded because wimpier layers were exposed there), or (b) that the folding introduced some weakness at the cusp of the fold (cracking where it was bent most sharply), making it more susceptible to erosion. Anyone care to comment on which is more common (is (b) even valid?) or fill us in on (c) none of the above? –Doug
