About Antarctica: Mt. Erebus
One of the challenges on the ice in Antarctica is finding our way. It’s easy to get lost when you’re surrounded by ice, snow and sky! So how do we remedy this situation?
We use landmarks! But these aren’t the landmarks we‘re familiar with back home. There are no businesses, street signs or tall buildings to help us find our way. We use land features to orient ourselves! Some of these include Tent Island, Hutton Cliffs, Big Razorback and Little Razorback Islands.
But none are as prominent as Mt. Erebus.
Mt. Erebus
While out seal searching, we can usually see Mt. Erebus gently smoking in the distance. That’s right, I said smoking. This is no ordinary mountain – this is a volcano!
Mt. Erebus is the southernmost active volcano in the world. It was discovered in 1841 by James Clark Ross. It was easy for him to spot – it was erupting!
Mt. Erebus erupts a lot, sometimes more than once a day! Check out this video of Mt. Erebus erupting!
Mt. Erebus also has one of only five constant lava lakes found in the world. A lava lake is just what it sounds like – a lake of molten (liquid) lava contained in the crater of a volcano! Most volcanos don’t have lava lakes because the lava on top has hardened; in other words, it’s no longer molten.
Mt. Erebus often spews lava and lava bombs, which are globs of gooey lava that are shot in the air by the force of the eruption. These lava bombs can fly as far as a mile away from Mt. Erebus and can be up to ten feet wide! That made me a bit nervous – what if I got hit in the head with a lava bomb? Not to worry! My research team assured me this is very unlikely. The only people really at risk are the researchers who study Mt. Erebus, and they get a lot of training in lava bomb dodging!
Because of these lava bombs and constant eruptions, this mountain is actually covered in crystals. When lava cools quickly, it turns into crystals, and these crystals can be found all over the mountain.
Mt. Erebus is also surrounded by ice caves. These are incredibly beautiful caves that are formed by cracks in the earth’s crust. These cracks – or fumaroles – emit hot gases which melt the surrounding snow and ice. This makes a cave. Venturing into these caves can be dangerous. Sometimes researchers have to rappel down into them! It would be very exciting, but I think I’ll leave that to the professionals!

Here are some more fun facts about Mt. Erebus!
Mt. Erebus is the second tallest volcano in Antarctica.
Mt. Erebus is 12,451 feet tall!
Erebus is classified as an ‘ultra’ mountain, which means that its summit reaches more than 10,000 feet above sea level.
Mt. Erebus is one of 35 volcanos in Antarctica.
Mt. Erebus is named after one of James Clark Ross’s ships, Erebus.
The lava in the lava lake is about 1,700 degrees F.
