Crater Lake National Park
This panorama of Crater Lake was taken by James Blakeway. Perched at the crest of the Cascade Mountain Range in the state of Oregon, Crater Lake National Park is one of the snowiest inhabited places in America, receiving an average of 44 feet of snow per year. Open year-round, the park protects the deepest lake in the United States, Crater Lake, known for the purest water on earth and depths up to 1,943 feet. The lake rests inside a caldera formed about 7,700 years ago, when a 12,000-foot-tall volcano collapsed following a major eruption. Today, the volcano’s outer slopes are blanketed with old-growth forests and harbour a variety of plants and animals, including several rare species

Hoover Dam This aerial panorama of Hoover Dam, with the Colorado River in the foreground, was taken by James Blakeway. Considered one of America's Seven Modern Civil Engineering Wonders, the dam project was authorized by Congress in 1928 to control floods, provide irrigation water and produce hydroelectric power. Construction on the dam began in 1931 and was completed in 1936, more than two years ahead of schedule. The dam was dedicated on September 30, 1935, by President Franklin Roosevelt, but was controversially named in honor of President Herbert Hoover. Hoover Dam is a National Historic Landmark and attracts nearly a million people who tour the dam each year. |
Hoover Dam
This aerial panorama of Hoover Dam, taken by James Blakeway, captures a beautiful sunny day over the dam, with Lake Mead in the background to the left. Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the US states of Arizona and Nevada. It was constructed between 1931 and 1936 during the Great Depression, and was dedicated on September 30, 1935, by President Franklin Roosevelt. Its construction was the result of a massive effort involving 21,000 workers, 45,000,000 pounds of reinforcing steel and 4,360,000 cubic yards of concrete. The dam's generators provide power for public and private utilities in Nevada, Arizona and California.
Yellowstone National Park – Lower Falls
This panorama of Yellowstone National Park features the popular park vista known as Lower Falls, one of two famous waterfalls on the Yellowstone River. As the Yellowstone River flows north from Yellowstone Lake, it leaves the Hayden Valley and plunges first over Upper Falls and then a quarter mile downstream over Lower Falls. Lower Falls is 308 feet high, or almost twice as high as Niagara Falls although the volume of water is not comparable to Niagara. The Lower Falls of the Yellowstone is still the largest volume major waterfall in the Rocky Mountains of the United States. The Yellowstone River is the longest undammed river in the continental United States.
