Federation, California, West Foothills of the Sierra Nevada, Yosemite National Park.
The park, spanning approximately 1,100 square miles, once famed for its California Redwood Forest, had been completely cleared. Creeks and waterfalls had become trenches, while cliffs were outfitted with firing positions. Rugged pathways once suitable for tourists had been flattened into broad avenues by road rollers. Small animals were driven away by the roaring sounds of drilling, and the soft glacial soil was dug up as a network of underground defense fortifications began to be constructed at an astonishing pace.
Freight trucks incessantly delivered batches of hot weapons to this terrestrial paradise. Two Federal Army corps were stationed here. Supported by strong logistics and technology, they transformed Yosemite National Park into a military fortress in just a few days.
