On Sunday, January 31st, Big Bend rangers made a traffic stop that resulted in the seizure of approximately 53 pounds of marijuana. Over the course of a few hours earlier in the day, several rangers developed reasonable suspicion that a rental Chevy SUV had come to the park to pick up either a load of undocumented aliens or drugs. Surveillance of the vehicle was conducted by rangers as the vehicle moved throughout the park. It was later seen at the Boquillas Canyon overlook, which sits directly on the Mexican border at the bank of the Rio Grande. The operator of the vehicle was subsequently contacted for excessive speed on Route 12 within the park. The driver granted a consent search of the vehicle and the marijuana was found. Local DEA agents responded to assist.
