Scientists may have accidentally discovered magma bubbling beneath a volcanoless region of Alaska.
Many geologists have long thought that the highest peak in North America, Denali (formerly known as Mount McKinley), should be a volcano, because it's positioned just 60 miles (100 kilometers) above one of the most active fault zones in the U.S. Yet, despite being bordered by volcanoes to its east and west, this area has not shown the telltale signs of molten rock or hot springs at its surface. This prompted a nickname for the region: the Denali volcanic gap.
