The River That Flows Uphill: A Journey From the Big Bang to the Big Brain
Written in the form of a scientists diary of a two-week float trip down the Colorado River through the Grand Canyon. There we find rocks of great age, fossils, dwellings of Stone Age peoples, and experience the land much as our ancestors did during all those untold generations in the dimly remembered world from which we somehow took flight.
