Constructing the Canyon Road not only took lots of man hours, but lots of dynamite too. Based on this picture, there weren’t too many safety procedures in the 1920s. There are sticks of dynamite lying around the box and at this man’s feet!
This photo has some fabulous detail. If you zoom in you can even read the name of the explosives box — Trojan Powder, from the Trojan Powder Co., out of Oakland, Calf. The company no longer exists, but they did create quite a mess from 1906 to 1965, and had to do some environmental clean up in the 1990s.
