Trail Codes in McDowell Preserve Help Hikers, Rescuers

At one time, if a hiker got hurt within Scottsdale’s 17,000 acres of McDowell Sonoran Preserve and someone managed to call 911 for help, the call was routed to the same address, 18333 N. Thompson Peak Parkway.

No matter if the hiker was stranded on the other side of the preserve, firefighters were routed to this address. As more trailheads opened to the public, the need to install GPS markers in the preserve increased.
