I am the type of room you cannot enter or leave. Raise from the ground below I could be poisonous or a delicious treat.
Never resting, never still. Moving silently from hill to hill. It does not walk, run or trot. All is cool where it is not. What is it?

It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
