River trip, part 2 ... the show

They drove pickup trucks loaded with huge floodlights up the road at the base of the cliff on one side of the canyon as a narration with music played.

It told the story of the development of the land over millions of years with light and shadow.

They crossed a bridge and continued the story down the other side of the canyon to tell the story of the people who have lived here.

Then they turned off the lights and we drifted down the river with lovely music as we contemplated the universe.
