Running hot and cold.

When Mt. St. Helens erupted in 1980, it melted an estimated 4.6 nillion cubic feet (ft.sup.3.) of snow and ice that had previously graced its slopes and unleashed a torrent of mudflows and floods on the valleys below. Partially because of this, researchers at the U.S. Geological Survey (USGS) are using radar and aerial photographs to measure the amount of snow and ice resting on other volcanos in the Cascade mountain range.

The results (all in ft.sup.3.) for four volcanos, released last week in a new report, are: 156 billion for Mt. Rainier in Washington, 12.2 billion for Mt. Hood in Oregon, 5.6 billion for Three Sisters in Oregon and 4.7 billion for Mt. Shasta in northern California. According to USGS, no eruption forecasts have been issued for any of these volcanos, although none of them is extinct.
