Montana: Glacier NP: stone patterns, natural abstracts

Look down! At your feet in Montana's Glacier National Park, be amazed at the colorful billion-year-old rock patterns and fantastic natural abstracts. Over 1.6 billion to 800 million years ago, shallows seas deposited sediments into a myriad of layers. During the tectonic formation of the Rocky Mountains 170 million years ago, the Lewis Overthrust shoved the sedimentary rocks 50 miles horizontally and piled the Lewis and Livingston Ranges on top of newer Cretaceous age rocks. Since 1932, Canada and USA have shared Waterton-Glacier International Peace Park, which UNESCO honored as a World Heritage Site (1995) containing two Biosphere Reserves (1976).
