Accompanied by columns of smoke, skiers and boarders take mostly intermediate slopes back into the valley near Nicolosi.
From many decades of such experience, geologists have excellent data that guides proper usage of each of these tools, and they don't include gross misuse of potassium-argon dating. In combination, these tests give a far more complete and accurate picture of a rock's true age than just a single potassium-argon test could.
