The icy slopes made Frost Worm Valley an oven, with how extremely cold and brutal the conditions were. However, the Blue Bloods loved this area, and deemed it perfect for sleading and relaxations. It stetched for miles, so some dwarves would go down shirtless, half naked after running the forges all day to cool off. They would slide for almost an hour, if they let it go right down to the end, and so that too was another aspect they loved, and soon they had erected a contraption to pull them up the mountain faster than having to walk all the way up.
