Brick-Red
Clinker forms when coal veins catch fire and bake the rock above, changing it into this much harder, red rock.
Brown and Tan
Sandstone, siltstone, and mudstone are sediments washed down from the Rocky Mountains.
Black
Coal is the remains of ancient plants and animals that lived in Everglades-like swamps.
Blue-grey
Bentonite clay is made of ash from distant volcanoes.
