Mount Shasta is in Northern California, and you pass it when driving on I-5 just north of Redding.
It has erupted on average every 600 years for the last 4,500 years. It’s still classified as an active volcano.
Here is another interesting fact about that volcano:
In 2002, scientists made the first detailed survey of Mount Shasta’s glaciers in 50 years. They found that seven of the glaciers have grown over the period 1951–2002, with the Hotlum and Wintun Glaciers nearly doubling, the Bolam Glacier increasing by half, and the Whitney and Konwakiton Glaciers growing by a third.
So much for global warming …
