Last December 21st, rangers detected a group of marijuana smugglers moving through the park. Despite the group’s use of carpet overshoes designed to obscure their tracks, the rangers were able to track them for about five miles over rough terrain, then apprehend and arrest one member of the group. They also seized seven backpacks containing 369 pounds of processed marijuana. A special agent from the NPS Investigative Services Branch assisted with case investigation and federal prosecution. On July 28th, the man who was arrested was sentenced to three years in federal prison and three additional years’ probation for violations of 21 USC 846 (possession of marijuana with intent to distribute). Upon completion of his prison term, he will be turned over to immigration officials and barred from legally re-entering the U.S.
