The seven remaining teams headed to Calgary where they struggled to stay “in line” during a difficult Roadblock. In this leg's Roadblock, one team member had to properly learn and perform a classic Canadian line dance. If they could impress the judge, a professional line dancer, they would receive their next clue – if not, they have to start all over again. In the Detour, teams had to choose between Lump by Lump and Bone by Bone. In Lump by Lump, teams traveled to the Atlas Coal Mine and rode a locomotive called "Linda" to the Wash House, where they dressed up in coal mining outfits. They then had to shovel coal into a mine cart so that it overflowed and touched all four edges of the cart. After properly hanging their teams' dogtag on the cart, they would receive their next clue; if the cart wasn't ready for haulage, they would have to start over and keep shoveling coal. In Bone by Bone, teams traveled to the Tyrrell Museum where they studied a mounted display of a dinosaur's skeleton. They then had to enter the specimen preparation laboratory and completely build a model of the same skeleton from their memory.
