Trapper Dan's Needle is a towering structure near Icicle Lodge.
Trapper Dan built the hollow Needle so he could hide animal furs inside in order to smuggle them without paying tax.
In 2007, Nancy first discovers the needle after following some wolf tracks. She sees a torn piece of black cloth halfway in the needle, suggesting that it can open up.
During the course of her investigation, Nancy learns that Yanni Volkstaia hid his explosives in there. With his secret discovered, he blows up the needle.
