Marble-ous Hot Rocks

Over a billion years ago, the Earth went through tremendous upheaval, with heat and pressure transforming rocks existing at that time to metamorphic rocks we see today. In this lime kiln, built by the McLachlin lumber Company sometime in the mid- to late-1800s, marble (metamorphic rock visible along this trail) and sedimentary limestone was burned. The burned rock was buried to be later mixed with water to make mortar for brick and foundation work, and paint known as “whitewash” for beautifying buildings and barrels. The paint also contained an antibacterial agent.
