What is the Hashknife Pony Express?
The original Pony Express lasted eighteen months in 1860–61. Arizona’s has lasted since 1958. Every winter, riders of the Hashknife Posse — the Navajo County Sheriff’s volunteer search-and-rescue unit, named for the brand of a legendary 1880s cattle outfit — saddle up in Holbrook, on the high plateau near the Petrified Forest, and carry sacks of U.S. Mail roughly 200 miles to Scottsdale: down through Heber, over the Mogollon Rim to Payson, along the Beeline to Fort McDowell, and into town.
It is not a reenactment with prop letters. The U.S. Postal Service sanctions the ride, the riders are sworn in as mail messengers, and the letters — nearly a thousand in 2026, around 20,000 in peak years, from as far as Europe and Asia — are delivered through the regular mail after they arrive, bearing a cachet nobody else can get. It is recognized as the oldest officially sanctioned Pony Express in the world, and it began, characteristically, as a stunt: a dozen riders delivering a single invitation to the governor to come to the Parada del Sol rodeo.
For most of its history the arrival has doubled as the opening bell of Scottsdale’s Western Week — riders loping onto Marshall Way at noon the Friday before the parade. It is the single most authentic thing the city does all year, and it costs nothing to watch.
Watching it — and riding along by mail
The arrival is the event. The ride takes three days, but Scottsdale sees only the last leg: a relay team coming in at a lope, the mail handed off with some ceremony, the posse in full regalia, a short program of speeches and photographs. It is over in twenty minutes. Arrive an hour early, find the rail, and bring a camera with a fast shutter.
Where it finishes has moved. From Western Week’s launch in 2017 through 2025, the finish was outside Western Spirit: Scottsdale’s Museum of the West on Marshall Way in Old Town — the right place, steps from the galleries and the parade route. In 2026 the ride was rescheduled to late March and finished at Arizona Boardwalk in the Talking Stick district beside the aquarium. Check the Posse’s schedule page each winter for the year’s date and finish line before you plan around it.
Ride along by mail. This is the local’s move. Address a letter to yourself (or anyone), stamp it, seal it inside a second stamped envelope addressed to the Hashknife Pony Express, P.O. Box 118, Holbrook, AZ 86025, and mail it before the posted deadline. Weeks later it arrives with the cachet and a story. Collectors have done this for decades; teachers do it for whole classrooms.
Pair it. The traditional Friday arrival leads into the Gold Palette ArtWalk that evening, the Arizona Indian Festival on the Civic Center lawn that weekend, and the parade Saturday morning. Even in a year the ride moves, Western Week runs its own Pony Express program in Old Town.
The brand, the posse, and the rim
The name is older than the ride. The Aztec Land & Cattle Company — the “Hashknife outfit,” after its brand’s resemblance to a chuck-wagon chopping tool — ran a million acres of northern Arizona in the 1880s with a crew notorious enough to fuel the Pleasant Valley War. When Navajo County’s sheriff organized a volunteer posse in 1955 for search-and-rescue on the county’s vast backcountry, its members claimed the brand as a badge of local memory. Three years later they invented the ride.
The 1958 mission was civic diplomacy: Scottsdale’s young Parada del Sol needed a governor, and a letter delivered by horse from 200 miles away was a better invitation than a phone call. Governor McFarland came. The following year the posse rode again with more letters, and somewhere in the 1960s the Postal Service made it official — each rider raising a hand to be sworn in as a mail messenger before departure, a ceremony that continues.
The route is the point of pride. Holbrook sits at 5,000 feet; the ride drops off the Mogollon Rim into Payson, follows the Beeline through the Mazatzals to the Fort McDowell Yavapai Nation, then crosses into the Valley — three days in February weather that can mean snow at the start and 75 degrees at the finish. Riders cover it in relay legs of a mile or two at a lope, the mochila passing hand to hand, a support crew of nearly equal size following in trucks.
Why Scottsdale keeps it
The city has built and lost a lot of Western pageantry — the Sunshine Festival, the old rodeo grounds, half the storefronts on Main Street. The Pony Express survives because it isn’t Scottsdale’s to run; it belongs to a county two hundred miles north, and Scottsdale is simply its destination. That gives the arrival an authenticity no tourism office could manufacture: the riders are ranchers and deputies, the horses have just done real miles, and the mail in the bags is going to actual mailboxes. When the posse comes in at noon and the sheriff hands over the sacks, “The West’s Most Western Town” is, for twenty minutes, exactly what the sign says.
