Mount Rainier

                 Mount Rainier is a massive stratovolcano located 54 miles (87 km) southeast of Seattle in the state of Washington, United States. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m). On clear days it dominates the southeastern horizon in most of the Seattle-Tacoma metropolitan area to such an extent that locals sometimes refer to it simply as "the Mountain." On days of exceptional clarity, it can also be seen from as far away as Portland, Oregon and Victoria, British Columbia. It had an elevation of 4,392 m (14,411 ft). 
                 With 26 major glaciers and 36 sq mi (93 km2) of permanent snowfields and glaciers, Mount Rainier is the most heavily glaciated peak in the lower 48 states. The Carbon, Puyallup, Mowich, Nisqually, and Cowlitz Rivers begin at eponymous glaciers of Mount Rainier.

Chihuahuan Desert

                  Chihuahuan Desert is a desert, and an ecoregion designation, that straddles the U.S.-Mexico border in the central and northern portions of the Mexican Plateau, bordered on the west by the extensive Sierra Madre Occidental range, and overlaying northern portions of the east range, the Sierra Madre Oriental. 
                   The Chihuahuan Desert is higher in elevation than the Sonoran Desert to the west, mostly varying from 600–1,675 m (1,969–5,495 ft) in altitude. As a result, it tends to have a slightly milder climate in the summer (though usually daytime June temperatures are in the range of 35 to 40 °C or 95 to 104 °F). Winter weather varies from relatively mild to quite cold depending on altitude and the ferocity of northerly winds. Precipitation is somewhat more abundant than most of the southern Great Basin , the Sonoran, and Mojave deserts, however it is still usually less than 254 millimeters (10.0 in) per year.

Mauna Kea

               Mauna Kea is a volcano on the island of Hawaii. Standing 13,803 ft (4,207 m) above sea level, its peak is the highest point in the U.S. state of Hawaii. However, much of Mauna Kea is below sea level; when measured from its oceanic base, its height is 33,500 ft (10,200 m)— more than twice Mount Everest's base-to-peak height of 3,650 to 4,650 metres (11,980 to 15,260 ft). 
               Mauna Kea is one of five hotspot volcanoes that form the island of Hawaii, the largest and youngest island of the Hawaiian-Emperor seamount chain. Of these five volcanoes, Mauna Kea is the fourth oldest and fourth most active. Mauna Kea is the only Hawaiian volcano with distinct evidence of glaciation. Similar deposits probably existed on Mauna Loa, but have been covered by later lava flows.

Lake Huron

              Lake Huron (Lac Huron) is one of the five Great Lakes of North America. It is bounded on the east by the Canadian province of Ontario and on the west by the state of Michigan in the United States. By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of 23,000 square miles (59,600 km2) making it the third-largest fresh water lake on Earth. Lake Huron is separated from Lake Michigan, which lies at the same level, by the narrow Straits of Mackinac, making them geologically and hydrologically the same body of water (sometimes called Lake Michigan-Huron). Lake Superior drains into the St. Marys River at Sault Ste. Marie which then flows southward into Lake Huron. 
              In Lake Huron lies Manitoulin Island - the largest lake island in the world. The following settlements are on the banks of Huron lake: Bay City, Alpena, Cheboygan, St. Ignace, Port Huron in Michigan; Goderich, Sarnia in Ontario.

Great Basin Desert

            Great Basin Desert is the largest U. S. desert. It is bordered by the Sierra Nevada Range on the west and the Rocky Mountains on the east, the Columbia Plateau to the north and the Mojave and Sonoran deserts to the south. Rainfall within the Great Basin Desert region varies from 7 - 12 inches of rainfall per annum. 
             The Great Basin Desert is a cold desert caused by the rain shadow effect of the Sierra Nevada to the west. The predominant flora are continuous shadscale and sagebrush. The ecotone demarcating the north of the Mojave Desert is the edge of Creosote Bush habitat and is also the south demarcation of the Great Basin shrub steppe and Central Basin and Range ecoregions. The ecotone is established by elevation increase, temperature decrease at higher elevations, and rainfall.

Great Salt Lake Desert

            Great Salt Lake Desert is a large dry lake in northern Utah between the Great Salt Lake and the Nevada border which is noted for white sand from evaporite Lake Bonneville salt deposits. Several small mountain ranges crisscross through and along the edges of the desert, such as the Cedar Mountains, Lakeside Mountains, Silver Island Mountains, Hogup Mountains, Grassy Mountains, and Newfoundland Mountains.
            The Great Salt Lake Desert is cool during the winter and includes unusual plants adapted to the dry conditions. Most of the desert receives less than 8 inches (200 mm) of annual precipitation. The salt crust covering the desert reforms each year when the rain evaporates.
