110-115 foot jump from the “Devil’s Diving Board” into Guernsey Lake in Guernsey Wyoming. This jump takes 2.63 to 2.7 seconds (depending on when you start the time). Chris is going almost 60 mph when he hits the water. Put a stopwatch on it. This is a legit 110 foot jump. NOTE: This jump is from the cliff directly below Devil’s Diving Board (8-10 feet below) The actual Diving Board 120+ feet high, is considered too unstable to jump from. Filmed by Aaron, witnessed by Josh, Sean and Anthony.
