Glen Canyon Dam Switchyard

The switchyard at the top of Glen Canyon Dam takes hydro generation off the Colorado River and puts it onto 345kV lines toward Phoenix, with a 230kV tie east into New Mexico. Long strings of insulators, lattice dead-ends, and disconnect stacks, all sitting in the red-rock canyon at Page.

Work in that setting is as much about access, footing, and the heat as it is about the steel.
