Mt Erebus is the second largest active volcano in Antarctica and the 6th highest ultra mountain in the world (an ultra mountain is a peak that is at least 4921 ft above the next highest peak around it). Its basically a measure of “mountain independence . Its also visible from drill camp every day.
The mountain has been continuously active since 1972 as you can see in the picture from the steam spouting out the top. There’s lava in there. It also appears to be deceptively close as if its right behind the peak in the foreground. Its actually 30 miles away.
This clearly isn’t my picture but that’s the business going on inside Mt. Erebus.
