America's Toughest Jobs

The 12 remaining contestants remain in Alaska to learn how to navigate one of the most dangerous highways in North America as truck drivers.

Still up in Alaska, the 11 remaining contestants take on the job of searching for gold in a glacier fed river.

Now in the lower 48 the contestants take on the task of monster trucks.

This episode finds the contestants challenged to work on an oil rig, which includes lugging pipes, changing the bits and drilling in the mud.

The contestants find themselves being shoved around inside a wooden barrel by a bull to get the feel of his power as they will attempt to try bullfighting. They will receive grades on how well they protected the riders.

The remaining contestants are tested in their ability to work in heights when they join a bridge crew.

For their next job, the six remaining workers travel from the Port of Los Angeles, to Port Angeles, Washington, the heart of lumber country. Josh tells them that their job is logging. He introduces their boss, Gabe Rygaard, owner of Rygaard Logging. Josh explains that the mortality rate for logging is 20 times higher than the average American job. And, that losing limbs is common. Josh says they will be judged on skill, attitude and how hard they work.

The five remaining workers go to the heart of the Alaska range, Denali National Park. For over 100 years, adventurers have traveled there to climb Mt. McKinley, North America's highest peak. Since 1976, over 700 climbers have required rescue and 100 have died. Temperatures drop to minus 100 degrees Fahrenheit and winds regularly reach 100 miles per hour. The difference between life and death on Mt. McKinley is a guide; the next job the contestants will take on. To get there, they land directly on a glacier in a small plane.

The final episode finds the four remaining workers going back to 3 of the hardest jobs, logging, oil rigging and crab fishing where a winner will be determined. The prize money will be all the salaries combined from each job performed.
