- Phosphorus (Wikipedia)
Phosphorus is a chemical element; it has symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth’s crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate.

At first glance, Tenino might seem like your average small town, but what you may not know is that pieces of this town can be found all over North America. Between 1889 and the 1930s, multiple quarries in Tenino produced sandstone for construction all along the west coast.
