Turnoff to Boulder City, Nevada.

Looking southwest. The top photo is from the L.F. Manis collection (#100-1113) at the University of Nevada, Las Vegas, and was taken ca. 1935. I took the lower photo on 13 June 2011.

There's been just a bit of development! I think the exact original photography stance is now under the modern highway. Note, however, that not only is the big water tank on the skyline still there, but also the building skylined on the knoll to the right (outlined). I think it was one of the government's original offices for the Boulder Canyon Project (Hoover Dam).
