The phosphate was mined by pickaxe, at a rate of about 15 acres per year, until the advent of the steam shovel created a mining boom by the 1920s. The town of Nichols was a typical mining town of the period, with a company store and company housing. Phosphate mining peaked in Bone Valley during the early 1980s, but by 1990 foreign reserves were replacing the need for U.S. global supply, and ...
