Diorama: "Boulder Dam" (Hoover Dam)

This original diorama requisitioned on August 15, 1935, for the Bureau of Reclamation's exhibit alcove for the U.S. Department of the Interior Museum depicts a somewhat aerial view of rocky gorge walls with Arizona/Nevada's Boulder Dam, officially renamed Hoover Dam in 1947, visible in the middle distance. Cables span the gorge from left to right, and a red cable car is suspended in front of the dam. Water is jetting out from the release valve about a third of the way up the canyon wall on the left. Water is coming out with considerably less flow from the four additional gates downriver at water level, two on each side.
