On the morning of July 29, Phoenix firefighters got a call about a hiker in trouble on a ridge near Tatum Boulevard and Lincoln Drive. A 72-year-old man was dizzy, stuck, and unable to walk himself down. A news helicopter caught the moment crews hoisted him off the rock and into the air. He turned out to be Glen Keane, the Academy Award-winning animator behind some of Disney's most famous hand-drawn characters, and the mountain he'd been climbing was Mummy Mountain, the low, humped ridge that sits almost dead center in the Town of Paradise Valley.
If you live anywhere south of Doubletree Ranch Road, you've looked at that ridge a thousand times. It's the backdrop behind the pool, the shape that catches the last light before Camelback does. What most residents don't know, and what Keane's rescue quietly exposed, is that Mummy Mountain doesn't work like the mountain it resembles. Camelback has rangers, signed trailheads, and a public system built to manage exactly the kind of emergency Keane had. Mummy Mountain has none of that, and the reason isn't neglect. It's ownership.
A Mountain Nobody Manages The Way You'd Expect
Every other major peak visible from a Paradise Valley backyard belongs to a public preserve system. Camelback sits inside the City of Phoenix's Echo Canyon Recreation Area. The McDowell range to the north falls under Scottsdale's McDowell Sonoran Preserve, a 30,500-acre network with marked trailheads, volunteer greeters, and a preserve department that answers to the city. Mummy Mountain is the one exception. According to Wikipedia's entry on the peak, sourced from Town of Paradise Valley records, it's the only summit in the Phoenix Mountains that was never absorbed into the Phoenix Mountain Preserve. Instead, its upper slopes are held by a private charitable trust, and the Town of Paradise Valley itself is the closest thing it has to a landlord.
That distinction sounds bureaucratic until you try to actually reach the top. There's no visitor center. There's no ranger to greet you the way one might at a McDowell Sonoran trailhead. There's no official map showing where the public is allowed to set foot. What there is, instead, is a patchwork of private roads, a handful of cul-de-sacs where the pavement gives out into hillside, and one narrow, unofficial path that happens to start on resort property.
Keane's own warning after the rescue gets at exactly this gap between what the mountain looks like and what it actually is. He told local reporters not to assume the terrain is "the same way you saw it when you were a little kid." For a mountain with no signage, no closure system, and no ranger station, that's not a throwaway line. It's the entire problem.
How A $12,000 Purchase Became A 320-Acre Trust
The mountain wasn't always called Mummy Mountain. Early maps knew it as Windy Gulch, later Horseshoe Mountain. In the 1940s, a miner and businessman named Charles Mieg bought most of the property for roughly $12,000, according to Wikipedia's account of the parcel's history. Mieg thought the ridge's profile looked like a reclining Egyptian mummy, and when he began carving the land into residential parcels to sell, he marketed it under that name.
For decades after that, the mountain developed the way most of Paradise Valley did: private lots climbing the lower slopes, houses reaching higher each cycle. By the 1990s, residents and the Town Council worried that unchecked building would eventually reach the summit ridge itself, the same skyline every home in the area had been built to face. In November 1997, the Town created the Mummy Mountain Preserve Trust, a nonprofit charged with acquiring and holding the upper mountain before it could be subdivided further. The Town's own General Plan describes the goal plainly, to perpetuate the natural landscape, desert plants, wildlife, and scenic beauty of the mountain rather than let it fill in like everything below it.
The trust set out to protect roughly 320 acres along the ridge. By August 1999, according to the historical record cited on Wikipedia, it had secured 218 of those acres, most of it donated by property owners rather than purchased outright, with additional parcels coming from Maricopa County. Early supporters reportedly included historian Marshall Trimble and broadcaster Joe Garagiola, both lending their names to a fundraising effort that was, at its core, a neighborhood deciding to stop development a few hundred feet short of the top.
The Only Real Trail Runs Through A Resort's Back Lot
Here's the part that catches most people off guard: the trust protects the land, but it never built a trail system to go with it. The single maintained route toward the summit, known as Tyner's Trail, begins behind the Camelback Inn, the resort that has occupied Mummy Mountain's southern slope since 1936. To reach the trailhead, you walk through the resort's mock western village, cross a small bridge, and pick up the path from there. It's private property. The Camelback Inn allows hikers to pass through, but it's not a public trailhead in any official sense, and parking in the resort's lot without checking in first isn't something local guides recommend.
A few quick facts worth knowing if you've ever wondered what's actually allowed on the mountain behind your house:
- There is no city- or town-maintained public trailhead anywhere on Mummy Mountain.
- Tyner's Trail, the only developed route to the ridge, sits on land belonging to the Camelback Inn.
- A handful of neighborhood cul-de-sacs open directly onto the hillside, but these are informal access points, not managed trail systems.
- The upper 218-plus acres are protected from development by the trust, but protection from building isn't the same as public recreational access.
- No ranger station, trail counter, or heat-closure policy currently covers the mountain the way one covers Camelback or the McDowell Sonoran Preserve.
None of this makes the mountain off-limits. People hike it every week, usually by way of Tyner's or by picking their way up from a cul-de-sac at the base. It just means anyone who goes up is largely on their own once the pavement ends, which is precisely the situation Keane found himself in on July 29.
Why Camelback Gets A Heat Warning And Mummy Mountain Doesn't
The clearest way to see the gap is to compare Mummy Mountain to the peak it sits directly across from. Camelback Mountain falls under Phoenix's Trail Heat Safety Program, which closes the Echo Canyon and Cholla trails from 8 a.m. to 5 p.m. any day the National Weather Service issues an Excessive Heat Warning. The same policy applies to Piestewa Peak and parts of South Mountain. It exists because Phoenix Fire has been responding to a steady climb in mountain rescues. As of late June 2026, the department had already answered nearly 80 mountain rescues that year, a 50 percent jump over the same point in 2025, according to Phoenix Fire's own reporting to local news.
Mummy Mountain has no equivalent closure system. It was never part of the Phoenix Mountain Preserve, so the heat program that governs its neighbor across Lincoln Drive simply doesn't extend to it. When Keane needed rescuing, it was Phoenix Fire that responded anyway, crossing into Paradise Valley to make the save, a reminder that emergency response doesn't respect the same boundaries that govern trail management.
That's the piece of the picture worth carrying with you the next time you look up at that ridge from your own backyard. It isn't a park. It isn't fully private, either. It's a trust, stitched together one donated parcel at a time by neighbors who wanted the top of their skyline left alone, with none of the public infrastructure that makes its taller, more famous neighbor feel safer to climb. The mountain looks the same from every yard in Paradise Valley. The rules that govern it don't look like anything else in the Valley at all.
