Kettle Rock

Note the elliptical nature of this "kettle rock" in the surrounding slate.
Here a kettle rock nestles into the layers of slate along a mountain road. The rocks present a danger to underground coal miners because of their propensity to fall from the slate onto the earth floor below during excavation. The slate, too, is dangerous as its slabs can break away & fall onto miners, creating horrific cutting injuries.
