Over a million visitors a year tour Hoover Dam,
the highest concrete dam in the Western Hemisphere. The construction of the
dam, completed in 1935, had given people something positive to focus on during
the years of the Great Depression. Today,
it continues to regulate the flow of the Colorado River and provides a range
of benefits, including electricity for more than 1.3 million people and
irrigation for 1.5 million acres of land in the United States and Mexico. In
1955, the American Society of Civil Engineers (ASCE) named Hoover Dam one of
America's Seven Modern Civil Engineering Wonders. In 1984, the National Park
Service designated the dam a National Historic Landmark. In the same year, ASCE
designated it an Historic Civil Engineering Landmark.
We visited Hoover Dam on March 10, 2003. By about 9:00 in the morning, we were
driving across the dam from the Nevada side to the Arizona side, to an
uncovered parking area that would accommodate our medium duty truck. That
enabled us to view the dam and several of its structures as we walked across
it to the visitors center. There are four large
intake towers, two on each side of the river. (Only three are visible in
my photo.) Here is a
close-up photo
that gives a better indication of the size of these towers. (Notice the
people.) In the middle of
the dam is the
state
line marker between Nevada and Arizona.
At the visitors center, we descended below street level to purchase tickets
for the Discovery
Tour. After an introductory presentation by a guide, we were escorted to
the viewing area balcony above the
generator
room. Then we spent time on our own viewing the indoor exhibit halls.
There were film clips, photos, dioramas, and artifacts (such as this
wrench)
related to the
construction of the dam and the lifestyle of the workers. From inside the
visitors center, we looked out over the
dam
and Lake Mead to the north. From the observation deck on top of the
center, we watched the
Colorado
River continue on its way south.
Only part of our four-hour visit to Hoover Dam was spent in the visitors
center. In the Old Exhibit Hall, we saw a large relief map depicting the
Colorado River along with the dams from Colorado to the Mexican border. It was
interesting to locate some of the places we had already visited in the
Colorado River basin, including Brawley, Palm Springs, and Death Valley in
California, and Yuma in Arizona. There was a program associated with the map,
where locations were highlighted with light to correspond with the recorded
narration.
The areas immediately surrounding Hoover Dam itself contain many
architectural, design, and art features dating from the time of the building
of the dam. These seem rather "fancy" for such a utilitarian
structure, but they were designed to symbolize the contemporary view of the
dam as a spectacular achievement. Rather than try to describe these features,
based on my brief visit, I'll recommend you read about the sculptures
and star map at the Hoover Dam website.
A fairly recent (July 2000) addition to the art at Hoover Dam is the
High
Scaler statue. This sculpture is in honor of the builders of the dam,
represented here by the figure of a high scaler. These brave construction
workers dangled by ropes on the side of the deep canyon, hundreds of feet in
the air. Their tasks included setting dynamite charges and knocking away loose
rock after the blasts. They had to handle jackhammers and other tools while
suspended. An article
at the Hoover Dam website tells more about these courageous workers and their
dangerous job.
After leaving the site of the dam, we drove through the Lake Mead National
Recreation area. We stopped only briefly, at
Boulder
Beach, along Lake Mead.
