Leg 2 was based on the Lewis and Clark Expedition. Beginning at about 2:20 am, teams travelled over 600 mi (965 km), from South Dakota to Lexington Mine in Montana. Teams travelled 10,000 ft (3,050 m) into the mine and searched for the clue, a bucket (which was covered with snakes) inscribed with the words "bend the light." Teams discovered that by filling the bucket with water, the words "Wood Bottom Missouri River Montana" became visible by refraction. Team Southie Boys never found this clue, instead allying with Team Brown Family to leave the Wild Hanlons 11 hours behind them in last place. Teams travelled to the Wood Bottom Recreation Area, from where they would have to canoe in search of the next clue. Canoes could not be in the water after 5:30 pm and no teams arrived at the campsite early enough to launch, so all teams camped there overnight.
