Survive This - Season 1 Episode 10 Mountain

Adam, Jen, Kareem, and Zac must scale a vertical cliff face using climbing gear. The team are given one match, some pemmican, and a harmonica and told to build a fire, find water, and make a shelter. Adam and Jen collect firewood and complain that Kareem and Zac aren't pulling their weight. Kareem and Zac have difficult finding water, and Zac successfully lights the fire. The next morning, all four rappell back down the cliff. Les is critical of the failure to build a shelter, and how Adam and Jen turned survival into a competition.
