For 10 points, name this dam on the border between Arizona and Nevada.
Norwegian-born sculptor Oscar J.W. Hanson designed a memorial commemorating 112 worker deaths during this project, many from carbon monoxide poisoning in four horrifyingly-hot diversion tunnels. Harold Ickes (ICK-uhs) lambasted the eventual namesake of this project for "tak[ing] credit for something he had nothing to do with." The Six Companies, Inc. joint venture was founded to oversee this project, superintended by chief engineer Frank Crowe. The Bureau of (*) Reclamation received its first mass funding to carry out this project, which built four reinforced concrete intake towers feeding steel penstocks. This project was named at the time of its completion for Boulder Canyon, and it impounded Lake Mead. For 10 points, name this dam on the border between Arizona and Nevada.
