Mountain
Heights of mountains are typically measured above sea level. Using this metric, Mount Everest is the highest mountain on Earth, at . There are at least 100 mountains with heights of over above sea level, all of which are located in central and southern Asia. The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali, Mount Kilimanjaro and Nanga Parbat are possible candidates for the tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea ( above sea level) is the world's tallest mountain and volcano, rising about from the Pacific Ocean floor.
Up Denali 3D
Up Denali 3D is a stereoscopic (3D) documentary directed and produced by Thomas Riederer PE. The film portrays an epic adventure trek and technical summit climb of the highest mountain in North America. The mountain is also known as Mount McKinley. Denali has an altitude of 20,320’ and is one of the Seven Summits of the World. Situated in Alaska, in Denali National Park and Preserve near the Arctic Circle, a June Denali climb is spent entirely without darkness – essentially a single month-long “day”. And being so far North and so high, the entire climb, from flying into Base Camp via bush plane, to up-and-down the Kahiltna Glacier with repetitive carry-and-move snowshoe pack trips, to steep ascents near the 20,000’ Summit Ridge is spent entirely on snow.
