Duffy's Peak is like a really tall mountain. Imagine you're playing with your blocks, and you stack them up one on top of the other. The more blocks you stack, the taller your tower gets. Duffy's Peak is like a giant tower made of rocks and dirt and other things that are called "terrain."
Duffy's Peak is located in Antarctica, which is way down at the bottom of the world. It's so cold there that you have to wear very warm coats and hats and gloves so you don't get too cold.
People who are very curious about the world around us like to explore Duffy's Peak and climb to the very top. They use special equipment like ropes and harnesses to make sure they don't fall. At the top of Duffy's Peak, the air is very thin and the view is amazing.
But climbing a big mountain like Duffy's Peak is also very hard work. You have to be very strong and brave and patient, and you have to be willing to put in a lot of effort to make it to the top. But the feeling you get once you reach the peak is worth all the hard work; it's like you've climbed to the top of the world!
