For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil […]
SALT LAKE CITY – University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand […]

When voltage changed along the wire, a bell rang. Hessler then pulled on his boots and went outside to take black-and-white aurora photos. During the recent […]

If you draw a line from the Aleutians to volcanic features in interior Alaska, the curve goes over Denali’s summit. Like its neighbors in the […]
