Scope and content
Scene of Mayfield Dam construction. Workers on City Light's Mayfield Dam may be installing a giant bolt into the gorge's rock. These giant bolts, 30 feet long, 1 1/2 inches in diameter, were to make the rock more solid. Bethlehem Pacific Coast Steel claimed that these rock anchor bolts were the biggest ever installed. Workers are suspended on the platform high above the rocky gorge on the Cowlitz River. Bags of gravel or cement are piled on the platform along with construction equipment. 200,000 cubic yards of concrete would be used for the dam and powerhouse. The dam would cost 37 million dollars. Photograph ordered by the Bethlehem Pacific Coast Steel Corporation. (TNT 2-26-56, A-1, TNT 12-23-56, A-1)
