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 heads—devils to Clark, spirits to Native Americans. “With GPS you could walk right to the place, and, by George, there’s a painting on that rock,” says Harlan. |
