Grady Powell

When we last saw Grady Powell, he was leading teammate Eve Torres to victory on the NBC reality competition “Stars Earn Stripes.”

Powell, 26, a Westminster Christian Academy and Mizzou graduate who grew up in Chesterfield, returns to TV on Sunday, tackling the frozen wilderness for Season 2 of the National Geographic series “Ultimate Survival Alaska.” The series has four teams of three dropped in remote locations and challenged to reach an evacuation point before the clock runs out.
