Glen Canyon Dam Construction, 1962 or 63. Source unknown.

There’s a lot of good detail in this photo.It’s a good look at both spillways and the temporary coffer dam at the bottom of the picture. The concrete batch plant is visible on the canyon edge to the right. Water is visible exiting the right diversion tunnel, but not the left. The left diversion tunnel inlet was about 33 feet higher than the right tunnel inlet and was intended to be used only during high river flows. The parking lot for the lookout point is visible on the left, just above the bridge. The rectangular building along the highway on the left side of the bridge was the original visitor’s center. It was later moved into town and became the LARC center. I don’t remember what that acronym means. The rail-mounted cranes are visible on either side of the canyon. There was a 25-ton and a 50-ton crane on each side. In addition to transporting buckets of concrete to the dam, these cranes were used to transport people and equipment in and out of the dam site. Near the bottom right corner of the picture, you can see the tower structure holding the footbridge, and the footbridge is visible too. The dark area by that tower, that curves around the sandstone knoll, was the road/parking lot for the footbridge. You can still see the remnants of that road on Google Earth. Go take a look.

As a bonus, here’s a penciled version of this same picture that I had done because I think it looks cool…
