Grand Coulee Dam is truly magnificent to behold. Built from 1933 to
1975, it is 550 feet tall, from the 500 foot wide polished granite base, to
the 30 foot wide crest which supports a paved two lane road. When you
include the third power house, Grand Coulee Dam is almost 1 mile long. Did
you know there is enough concrete in the Grand Coulee Dam to build a 60 foot
wide highway four inches thick, from Los Angeles to New York City! ~
That is a 4 lane Highway 3,000 miles long.
The only remaining wonder of the 7 Ancient Wonders of
is the Great Pyramid of Giza, Built between 2,595 BCE& 2565 BCE
(over 30 Years and a work force up to 100,000 )
near the city of Cairo, Egypt.
The original height of the Great Pyramid of Giza is
approx 482 feet. It's
base covers over 13 acres.
In comparison, the base of the Grand Coulee Dam is almost four
times as large as the Great Pyramid built by the Pharaoh Khufu (Cheops).
It stands 550 feet in height, from the bedrock to the blacktop!
Pyramid, the Grand Coulee Dam has its galleries.
They serve for gate inspections and control, drainage, re-grouting, cooling,
purposes. There are over eight and a half miles of corridors
the inside of the Grand Coulee Dam.
In size, it is the 1st structure
created by man to exceed that of the Great Pyramid in all respects, which
was build [c. 2680 BCE]
Some will point out that the Great Wall
of China is Larger... Construction began around 700 BCE and was
completed in the late 16th century to it's approximate 1000 mile length and
varies between 18 and 30 feet in height. It was an on and off again project
which was built in
spanning almost 900 years and
as a whole, is larger than the Grand
Coulee Dam. Consequently, The Grand Coulee Dams completion in late 1942,
which tops the Great Pyramid, had a peak workforce of 7,700 and took a
little over 9 years to complete!
