Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]
Rocky Mountain National Park encompasses 265,461 acres (414.78 sq mi; 1,074.28 km2) of federal land,[1] with an additional 253,059 acres (395.40 sq mi; 1,024.09 km2) of U.S. Forest Service wilderness adjoining the park boundaries.[24] The Continental Divide runs generally north–south through the center of the park,[25] with rivers and streams on the western side of the divide flowing toward the Pacific Ocean while those on the eastern side flow toward the Atlantic.[26]
