This
spectacular sandstone opening is ancient. The people who inhabited
this cave and etched these petroglyphs are unknown. It's located at
the southeast end of the park, not too far above the Expedition's
July 13 camp. Most likely, neither Captain Lewis nor Captain Clark
discovered the cave. The Missouri runs about 500 yards at most from
here. The channel hasn't changed much since 1804. They camped on a
sand bar in the middle of the river. Rain and wind delayed there launch
until 7 AM. I imagine their full attention was on storm clouds that
morning. With limited visibility, their attention wasn't on the surrounding
area. |
