A image of electrical transmission towers and wires near Hoover Dam. Note: Boulder Dam was officially renamed Hoover Dam in 1947.

This photograph has four images. The first one (0272_0052) with the upside-down picture, has a handwritten inscription that reads, "View of hi-line and carriages on a double cable. First used on buckets. Was a little slow. These hi-lines stretching across the dam on a huge cable. Consist of several small cables in center, weaved together. In the center, outside, the carriages ride on smooth surface of one inch wide steel strips wrapped around the cables for a tight and smooth surface." The second image (0272_0053) reads, "'Pipe fitters' raising air and water pipe to a higher elevation for easier access." The third one (0272_0054) reads "'The water bag', a very popular item on Dam. Warning signs placed around, 'Do not drink water from taps on dam'. Arsenic in the water and in the mts. Once you get an open cut, you must avoid getting water from the dam in it. You have a good chance of arsenic poisoning. A boy in my dormitory got it. He broke out in sores at some spot. After long treatments it would heal, but two or three weeks break in another spot. Once in the blood, too bad." The fourth image (0272_0055) reads "Another good view. Stiffleg making a pour on dam nearest and #7 working in a lower pour - pours are numbered - from face to upstream face. 1-2-3 etc. across from wall to wall by alphabet, the slot (center) is between J & K."

An image of two vehicles traveling along Boulder Highway between Boulder City and Hoover Dam.

This photograph has three images. The first one (0272_0075) reads,"'Form Raising Crew,' 'Chris' the Boss - Webfoot 'Oregon' - Alright boys; let's go over the top - Reeve and I had the guts to climb over a swinging panel. If it was a large panel Slim would climb over after we secured it with a bolt on each end." The second image (0272_0076) reads, "'Form Raising Crew' - Pal Jake 'Georgia' - Georgia Cracker. ([Georgia as in:] 'Whar's the hammah? Who's got the bahr')." The third one (0272_0077) shows a particular day on site a week after Reeve's seventeenth birthday themed "something for the kid." The inscription reads, "The Crew. This form is hooked up to 'A' frame bars you see in foreground, is used to pry form from cement after it has been unbolted. Then it is jacked up to position and bolted up. Then load your 'A' frame - jacks, and block & tackle, and move to another job - some high pours have four panels - all swinging."
