1980   Mount Saint Helens, in Washington State, erupted, spewing ash and smoke nearly 63,000 feet into the air. Heavy ash covered the ground as small particles were carried by the winds all the way to the Atlantic coast.
1995   Near Ethridge, TN 6 TVA high-tension electric transmission towers were destroyed by an F4 tornado and were never found.
