If you spend a winter by yourself sleeping on a snow-covered, frozen lake in the Wyoming territory in the early 1800s, they might just name the area after you. That's how it went for Davey Jackson, the intrepid trapper whose name lives on in Jackson Hole and the town of Jackson. He is said to have spent the winter of 1829 camped alongside the biggest lake in what is now Grand Teton National Park, and for his trouble, they named the area, the eventual town, and that very lake after him.
