	Cave painting - Wikipedia, the free encyclopedia
		Cave art may have begun in the Aurignacian period (Hohle Fels, Germany), but reached its apogee in the late Magdalenian (Lascaux, France).

		Called a "Breaks" because of its abrupt, broken, and deeply eroded canyon, it is a 3.8-mile-long and 2.5-mile-wide amphitheater containing numerous ridges, cliffs, and spires eroded some 2,000 feet below the 10,300- to 10,500-foot elevation of the canyon.
		Iron and manganese oxide impurities produce an amazing variety of colors in the limestone cliffs that constantly change with the angle of the sun's rays.
		In the meadows bordering the six-mile-long rim drive, colorful wildflowers in season provide another resplendent attraction.
