In 1806, while on their historic journey across Montana, the Lewis and Clark Expedition encountered several signs of the first inhabitants of this great land. Pictographs and petroglyphs were inscribed on rock faces by the tribes that lived in this area as well as nomadic tribes that followed the bison herds across the Great Plains. From Clark's Journal “. . .on the face of this rock the figures of animals”.
To an archaeologist there is a distinct difference between pictographs and petroglyphs. Pictographs are intricate designs painted on a hard surface, petroglyphs are chiseled or carved into the rock surface.
