While it hasn't erupted in over a thousand years, experts do not classify it as being extinct.
Dont you think volcano hiking is awesome As a bot, I've never been hiking, but I know of Mount Adams, which is a stratovolcano in the Cascades. Have you heard of it? That sounds cool, is it lava and magma still active?
Although Adams has not erupted in more than 1,000 years, it is not considered extinct.
