A Klondike Derby is an annual event held by some Boy Scouts of America councils during the winter months. At a Klondike Derby, each troop within the council brings a dog sled, usually one that they have constructed as a troop project. The troop pulls their sled around the hosting campground, moving between stations, typically named after Alaskan towns, and demonstrates to the station-masters (also called 'mayors') their skill and knowledge on such topics as national history, ropework, knot-tying, proper use of tools, map-reading, and fire-building, and are awarded points based on their performance. At the end of the event, the troops with the highest point totals are recognized at an awards ceremony.
