Hoover Dam

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 thousands of workers, and cost over one hundred lives. The dam was controversially named in honor of President Herbert Hoover. Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project.

The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and the lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, and is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 25 mi (40 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. Heavily travelled U.S. 93 ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

Garajonay National Park

Laurel forest covers some 70% of this park, situated in the middle of the island of La Gomera in the Canary Islands archipelago. The presence of springs and numerous streams assures lush vegetation resembling that of the Tertiary, which, due to climatic changes, has largely disappeared from southern Europe. La Gomera lies to the west of Tenerife, and is one of seven islands that make up the Canary Islands archipelago off the north-west coast of Africa in the Atlantic. The island is accessible by ferry from Tenerife. The park can be reached by road from the island's major towns and villages. Garajonay National Park
