While we traveled the Coulee Scenic Corridor, we naturally wanted to touch base with one of the star attractions of the highway, the Grand Coulee Dam.
Below the dam, we got the full view of the enormous concrete project. Utilizing some 12,000,000 cubic yards of concrete, which we learned is equal to a 4' wide sidewalk going around the world -- twice! That is a lot of concrete!
The huge construction project required all kinds of skilled workers, including divers who worked well below the surface. Orinda was interested in trying this line of work out and is thinking about applying if they should need more divers in the future.
One of the most interesting things to Rick was the way the dam was constructed. Here, the slide rule is shown, which was the primary mathematical tool (other than the engineer's mind) used to build the dam. No computers, calculators or other modern tools used here!
The 550' high dam is a marvel of engineering and stretches over a mile across the Grand Coulee, which means large valley (from the French language). The dam is now over 70 years old and is still generating huge amounts of electricity and irrigating amazing land areas. While a bit out of the way, the dam is very well worth a visit!
