University of Missouri geographer James Harlan, in front, and historian Jim Denny of the Missouri Department of Natural Resources use a handheld global positioning system (GPS) to check the new map near Manitou Bluffs, not far from Columbia, Missouri. Here Lewis and Clark found rock paintings of human figures with antler-like protuberances on their headsdevils to Clark, spirits to Native Americans. With GPS you could walk right to the place, and, by George, theres a painting on that rock, says Harlan.
