Tuvalu
Because of the low elevation, the islands that make up this nation are vulnerable to the effects of tropical cyclones and by the threat of current and future sea level rise. The highest elevation is 4.6 metres (15 ft) above sea level on Niulakita, which gives Tuvalu the second-lowest maximum elevation of any country (after the Maldives). The highest elevations are typically in narrow storm dunes on the ocean side of the islands which are prone to overtopping in tropical cyclones, as occurred with Cyclone Bebe, which was a very early-season storm that passed through the Tuvaluan atolls in October 1972. Cyclone Bebe submerged Funafuti, eliminating 90% of structures on the island. Sources of drinking water were contaminated as a result of the system's storm surge and the flooding of the sources of fresh water.
List of U.S. states and territories by elevation
Which state or territory is ``highest ''and`` lowest'' is determined by the definition of ``high ''and`` low''. For instance, Alaska could be regarded as the highest state because Denali, at 20,310 feet (6,190.5 m), is the highest point in the United States. However, Colorado, with the highest mean elevation of any state as well as the highest low point, could also be considered a candidate for ``highest state ''. Determining which state is`` lowest'' is equally problematic. California contains the Badwater Basin in Death Valley, at 279 feet (85 m) below sea level, the lowest point in the United States; while Florida has the lowest high point, and Delaware has the lowest mean elevation. Florida is also the flattest state, with the smallest difference between its highest and lowest points.
Denali National Park and Preserve
Denali National Park and Preserve is a national park and preserve located in Alaska Interior, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompasses more than 6 million acres (24,500 km). The national preserve is 1,334,200 acres (5,430 km). On December 2, 1980, a 2,146,580 acre (8,687 km) Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga. The preserve is also home to tundra at middle elevations, and glaciers, rock, and snow at the highest elevations. The longest glacier is the Kahiltna Glacier. The park received 587,412 recreational visitors in 2016. Wintertime activities includes dog - sledding, cross-country skiing, and snowmachining.
