Made it

New arches are being formed and old ones destroyed.   The area is a virtual layer cake of
rock miles thick, a celebration of sandstones, mudstones, shales, salts and limestones all stacked
one upon another.  Each layer represents a different environment that existed here in the past.  Limestone might indicate the presence of an inland sea.  Sandstone is wind-blown sand dunes, shale contains the relics of a swampy river floodplain ruled by dinosaurs and giant trees. -  that's our earth - forever changing.
