From the Moab Times:
The National Park Service (NPS) is shedding some light on the semi-tractor and trailer that got stuck on Shafer Trail in Canyonlands National Park on Friday, Sept. 1 — and according to the park’s chief ranger, Scott Brown, the errant driver’s reliance on GPS resulted in the truck blocking visitor access for a number of hours.
According to Brown, the truck was operated by Bright Freight Solution of Stockton, Calif., and was headed from the west coast to the Intrepid Potash facility for a pick-up. The driver of the truck, which was empty when it turned onto Shafer Trail, claimed that his GPS unit instructed him to take the route on U.S. Highway 313 that led to Shafer Trail and then down to the potash facility.
That route, as it turns out, was not the best way to go.
The driver, who managed to detach his tractor from the trailer and venture down the trail before getting his rear axle stuck over the edge of a cliff, eventually called for help and, after an assessment by NPS rangers and Moab-based Nations Towing, the vehicle was turned around and backed up, clearing the trail for use.
The driver, who NPS officials declined to name, was not issued a citation in relation to the incident.
