Natural and Man-made Wonders of the World
One of the driving forces behind the creation of Las Vegas, Nevada and major sources of hydro-power for Los Angeles and its environs, the Hoover Dam is one of the largest dams in the world and was built between 1931 and 1936 by the U.S. Bureau of Reclamation (Stevens, 2007). The dam is currently named after President Herbert Hoover (Stevens). During the period from 1933 to 1947, though, it was known as Boulder Dam (Stevens). According to Harvey (1994), "About 90 percent of the hydro-power from Hoover Dam goes to southern California; another 10 percent to Las Vegas and southern Nevada" (pp. 226-228). The dam is situated on the Colorado River between Nevada and Arizona, and is.726 feet high and 1,244 feet long (Stevens). Lake Mead, one of the largest reservoirs in the U.S., was created by Hoover Dam and water from this lake is an important source for agricultural irrigation in southern California, Arizona and even Mexico (Stevens). According to Stevens, "Hoover Dam is part of Lake Mead National Recreation Area. Boulder City, Nevada, was built to house workers on the project" (p. 22,710). At 3,900 miles long, the Amazon River is enormous; although it is the second longest river in the world, it carries
Today, Grand Canyon hosts about five million visitors a year (Williams). Some of the stone heads have been destroyed by weather over the years, and no more are being made. During one of his many adventures, President Theodore "Teddy" Roosevelt almost lost his life while venturing down uncharted regions of the Amazon (Yarbrough, 2002). One of many such configurations in Britain, the geographic location of this particular henge is viewed by many as being attributable to its being a source of natural power, or at least a focal point for such power. According to O'Toole, "Although the most famous giant sequoia trees stand in Sequoia National Park, the Forest Service actually has more acres of sequoia groves in the Sequoia National Forest" (O'Toole, p. According to Williams (2006), "The awesome canyon we see today is about 277 miles long, ranges in width from 0. In his backpacking guidelines for the area, Engs advises that, "More than a century ago, it was Sierra Club founder John Muir's dream to protect the majestic giant sequoia trees in California. The amount of power involved suggests that there may be some basis for those who claim to even be able to hear the Northern Lights during particularly vivid displays. The thirty-mile-long Niagara River connected Lakes Erie and Ontario and tumbled 160 feet at its famous falls" (p. Twisting and bending in never-ending bands and ribbons of light, some observers claim they can even hear the atmospheric displays. There are literally millions of graphic images of Niagara, including etchings, paintings, and photographs" (p. Despite its fame, though, it would seem that mankind knows more about the moon than it does about many places along the Amazon River today. The encyclopedia entry for this natural phenomenon states, "The aurora borealis of the Northern Hemisphere is often called the northern lights, and the aurora australis of the Southern Hemisphere is known as the southern lights" (Aurora borealis, 2007, p.
