Here’s another aerial view of the Glen Canyon Dam construction site. This is looking upstream toward Wahweap creek. It’s a good look at the coffer dam, the early stages of the dam itself, and the power plant. The crane towers are visible on each side of the dam. If I remember right, there were two 25-ton towers and one 50-ton tower on either side. These crane towers moved back and forth along tracks. The road down to the visitor lookout site is visible on the right side of the canyon, coming off of US89. The oval shaped area was the parking lot and you can see the walking trail down to the lookout point. The footbridge is faintly visible in this photo too.
Lake Shore Drive, which was still dirt, is clearly visible. It was built and used for hauling gravel to the concrete batch plant at the dam site. Aggregate was trucked in to the batch plant from Wahweap Creek and dumped in an underground hopper at the base of the conveyor belt, visible in this picture near the end of the road. The aggregate was processed and conveyed to the concrete mixing plant seen in this picture on a large shelf cut out of the canyon wall. That concrete mixing plant was about twenty stories tall. The mixed concrete was dumped into a rail car that in turn, dumped the concrete into the buckets suspended by the cranes, for their trip to the topmost section of the growing dam. That’s the abbreviated story of the process. I always wanted to go inside that mixing plant but I never got the chance. Click on the image to enlarge it. Download it and check out the detail.
