Acadia National Park – Rocky Shoreline

The geologic history of Acadia National Park, Maine stretches back in time through millions of years to the formation of the oldest rocks on Mount Desert Island and continues to the present with the persistent forces of erosion. Evidence of this rich geologic past can be seen across the island, along rocky shorelines and atop windswept mountains.

Eye Level View of Half Dome

Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. The granite crest rises more than 4,737 ft (1,444 m) above the valley floor and stands nearly 8,800 feet above sea level
