INDIAN ART TO ENLIVEN BOULDER DAM POWER HOUSE
Old and new America will combine at Boulder Dam, when artists get to work with Indian designs.
In the control room, where workmen regulate tremendous forces of electricity and huge bodies of water, the expanses of gray wall are to be enlivened with Indian symbols of cloud and rain.
One of the designs, reproduced on the cover of this week’s Science News Letter, is taken from a prehistoric Indian bowl found on the site to be submerged by the new lake. It contains symbols for lightning (the step-like figures), clouds, water, and mesas.
