From executive producer Mark Burnett comes the epic summer series "Expedition Impossible," premiering THURSDAY, JUNE 23 (9:00-10:00 p.m., ET) on the ABC Television Network. The show features ordinary people doing the extraordinary in the biggest adventure of their lives. Adventurer, zoologist, big cat trainer and all around risk taker Dave Salmoni hosts the show.   "Expedition Impossible" follows 13 teams of 3, racing in a fun expedition across vast deserts, over snow capped mountains and through raging rivers in the beautifully exotic, fabled kingdom of Morocco. Each week a new stage of the expedition will be revealed to the teams. Will they crumble under the pressure of having to think clearly in the wilds of the great outdoors, or will they find a way to work together to complete their adventures? And if one person quits, the entire team is eliminated. After 10 stunning legs of competition with drama, comedy and great characters, one team will cross the finish line first to claim victory. Each winning team member will receive $50,000 ($150,000 total for the team) as well a new Ford Explorer.
