I'm not usually afraid of heights ...

Grand Coulee Dam (BPA/US Government Photo)


Taking a flock of sheep across the dam. 1947.

"The Grand Coulee Dam is almost a mile long at 5223 feet (1586 m). The spilway is 1,650 feet (503 m) wide. At 550 feet (168 m), it is taller than the Great Pyramid of Giza; all the pyramids at Giza could fit within the total area of its base. Its hydraulic height of 380 feet (115 m) is more than twice that of Niagara Falls. There is enough concrete to build a four-foot wide, four-inch deep sidewalk twice around the equator."
