The Yule Log Jam is an obstacle that premiered in the 4th season, Winter Wonderland, on the Pilot episode. It is comprised of 2 shaking and bucking logs you must cross by jumping. However, making the jump more difficult are vertical Sweeper Arms attempting to hit contestants while they jump. But on episode 2 of Winter Wipeout, they added a spanker bar to smack contestants on the head or the feet.
Jacob Chrisman (Episode 3, Winter Wipeout). He also won that episode.
