Jon >>Never? Never say never, Kamron — Nature has a funny way of proving such claims wrong with monotonous regularity. <g><< Poor comm tech, Needs work huh? its better than nutin.<g> >>Consider this scenario: River follows path of least resistance, and cuts a valley or even a canyon in soft rock to one side of a tower of harder rock, maybe an igneous intrusion. By and by, you have the river, then the igneous tower, then sedimentary rock all round the rest of the tower.<< I can buy this, the free standing mesas are a bit like that. The Grand Canyon, correct me if I'm wrong has consistency in the layers. One layer may be a different texture, density and material but the layer is very consistent. So it is a different sit. The carving of a canyon would maintain a V shape. How would you account for vertical walls in a canyons? Kamron Jon >>Never?
