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 cranes are visible on each side of the dam. There was one 25-ton and one 50-ton on rails on either side. The road down to the lookout site is visible on the right side. The oval shaped area was the parking lot and you can see the 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 gravel trucks. Aggregate was trucked in to the cement 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.
