The Smokey Mountains are a mountain range in Tennessee and North Carolina.
Riddler laid an ambush for the Team in a snowy valley. Cheshire served as bait, taking a charter plane from Asheville, and crashing it in the mountain range. After the Team arrived, the entire valley was locked with a forcefield, and Riddler's cohorts took on the young heroes. In the end, Riddler, Mammoth and Shimmer were arrested, though Cheshire got away.
