A blast raises clouds of dust in the canyon
Thick, rolling clouds of pale dust and darker smoke fill the lower part of the gorge and climb the rock walls; above them a road and a line of structures follow the contour of the slope. The clouds appear to rise from a blast in the canyon; the walls and the tunnels were opened with dynamite, and the work went on day and night.
