Who
Eric Clark, President and Chief Operating Officer of Mammoth and June Mountains, California

Why I interviewed him
Mammoth is ridiculous, improbable, outrageous. An impossible combination of unmixable things. SoCal vibes 8,000 feet in the sky and 250 miles north of the megalopolis. Rustic old-California alpine clapboard-and-Yan patina smeared with D-Line speed and Ikon energy. But nothing more implausible than this: 300 days of sunshine and 350 inches of snow in an average year. Some winters more: 715 inches two seasons ago, 618 in the 2016-17 campaign, 669 in 2010-11. Those are base-area totals. Nearly 900 inches stacked onto Mammoth’s summit during the 2022-23 ski season. The ski area opened on Nov. 5 and closed on Aug. 6, a 275-day campaign.
Below the paid subscriber jump: why Mammoth stands out even among giants, June’s J1 lift predates the evolution of plant life, Alterra’s investment machine, and more.
That’s nature, audacious and brash. Clouds tossed off the Pacific smashing into the continental crest. But it took a soul, hardy and ungovernable, to make Mammoth Mountain into a ski area for the masses. Dave McCoy, perhaps the greatest of the great generation of American ski resort founders, strung up and stapled together and tamed this wintertime kingdom over seven decades. Ropetows then T-bars then chairlifts all over. One of the finest lift systems anywhere. Chairs 1 through 25 stitching together a trail network sculpted and bulldozed and blasted from the monolithic mountain. A handcrafted playground animated as something wild, fierce, prehuman in its savage ever-down. McCoy, who lived to 104, is celebrated as a businessman, a visionary, and a human, but he was also, quietly, an artist.
Mammoth is not the largest ski area in America (ranking number nine), California (third behind Palisades and Heavenly), Alterra’s portfolio (third behind Palisades and Steamboat), or the U.S. Ikon Pass roster (fifth after Palisades, Big Sky, Bachelor, and Steamboat). But it may be America’s most beloved big ski resort, frantic and fascinating, an essential big-mountain gateway for 39 million Californians, an Ikon Pass icon and the spiritual home of Alterra Mountain Company. It’s impossible to imagine American skiing without Mammoth, just as it’s impossible to imagine baseball without the Yankees or Africa without elephants. To our national ski identity, Mammoth is an essential thing, like a heart to a human body, a part without which the whole function falls apart.

What we talked about
Mammoth’s new lift 1; D-Line six-packs; deciding which lift to replace on a mountain with dozens of them; how the new lifts 1 and 16 redistributed skier traffic around Mammoth; adios Yan detachables; the history behind Mammoth’s lift numbers; why upgrades to lifts 3 and 6 made more sense than replacements; the best lift system in America, and how to keep this massive fleet from falling apart; how Dave McCoy found and built Mammoth; retaining rowdy West Coast founder’s energy when a mountain goes Colorado corporate; old-time Colorado skiing; Mammoth Lakes in the short-term rental era; potential future Mammoth lift upgrades; a potentially transformative future for the Eagle lift and Village gondola; why Mammoth has no public carpets; Mammoth expansion potential; Mammoth’s baller parks culture, and what it takes to build and maintain their massive features; the potential of June Mountain; connecting to June’s base with snowmaking; why a J1 replacement has taken so long; kids under 12 ski free at June; Ikon Pass access; changes incoming to Ikon Pass blackouts; the new markets that Ikon is driving toward Mammoth; improved flight service for Mammoth skiers; and Mammoth ski patrol.
What I got wrong
* I guessed that Mammoth likely paid somewhere in the neighborhood of $15 million for “Canyon and Broadway.” I meant that the new six-pack D-line lifts likely cost $15 million each.
* I mentioned that Jackson Hole installed a new high-speed quad last year – I was referring to the Sublette chair.
* I said that Steamboat’s Wild Blue Gondola was “close to three miles long” – the full ride is 3.16 miles. Technically, the first and second stages of the gondola are separate machines, but riders experience them as one.
Why now was a good time for this interview
Talk to enough employees of Alterra Mountain Company and a pattern emerges: an outsized number of high-level execs – the people building the mountain portfolio and the Ikon Pass and punching Vail in the face while doing it – came to the mothership, in some way or another, through Mammoth Mountain.
Why is that? Such things can be a coincidence, but this didn’t feel like it. Rusty Gregory, Alterra’s CEO from 2018 to ’23, entered that pilot’s seat as a Mammoth lifer, and it was possible that he’d simply tagged in his benchmates. But Alterra and the Ikon Pass were functioning too smoothly to be the products of nepotism. This California ski factory seemed to be stamping out effective big-ideas people like an Italian plant cranking out Ferraris.
Something about Mammoth just works. And that’s remarkable, considering no one but McCoy thought that the place would work at all as a functional enterprise. A series of contemporary dumbasses told him that Mammoth was “too windy, too snowy, too high, too avalanche-prone, and too isolated” to work as a commercial ski area, according to The Snow Mag. That McCoy made Mammoth one of the most successful ski areas anywhere is less proof that the peanut gallery was wrong than that it took extraordinary will and inventiveness to accomplish the feat.
And when a guy runs a ski area for 52 years, that ski area becomes a manifestation of his character. The people who succeed in working there absorb these same traits, whether of dysfunction or excellence. And Mammoth has long been defined by excellence.
So, how to retain this? How does a ski area stitched so tightly to its founder’s swashbuckling character fully transition to corporate-owned megapass headliner without devolving into an over-groomed volume machine for Los Angeles weekenders? How does a mountain that’s still spinning 10 Yan fixed-grip chairs – the oldest dating to 1969 – modernize while D-Line sixers are running eight figures per install? And how does a set-footprint mountain lodged in remote wilderness continue to attract enough skiers to stay relevant, while making sure they all have a place to stay and ski once they get there?
And then there’s June. Like Pico curled up beside Killington, June, lost in Mammoth’s podium flex, is a tiger dressed up like a housecat. At 1,500 acres, June is larger than Arapahoe Basin, Aspen Highlands, or Taos. It’s 2,590-foot-vertical drop is roughly equal to that of Alta, Alyeska, or Copper (though June’s bottom 1,000-ish vertical feet are often closed due to lack of lower-elevation snow). And while the terrain is not fierce, it’s respectable, with hundreds of acres of those wide-open California glades to roll through.
And yet skiers seem to have forgotten about the place. So, it can appear, has Alterra, which still shuffles skiers out of the base on a 1960 Riblet double chair that is the oldest operating aerial lift in the State of California. The mountain deserves better, and so do Ikon Pass holders, who can fairly expect that the machinery transporting them and their gold-plated pass uphill not predate the founding of the republic. That Alterra has transformed Deer Valley, Steamboat, and Palisades Tahoe with hundreds of millions of dollars of megalifts and terrain expansions over the past five years only makes the lingering presence of June’s claptrap workhorse all the more puzzling.
So in Mammoth and June we package both sides of the great contradiction of corporate ski area ownership: that whoever ends up with the mountain is simultaneously responsible for both its future and its past. Mammoth, fast and busy and modern, must retain the spirit of its restless founder. June, ornamented in quaint museum-piece machinery while charging $189 for a peak-day lift ticket, must justify its Ikon Pass membership by doing something other than saying “Yeah I’m here with Mammoth.” Has one changed too much, and the other not enough? Or can Alterra hit the Alta Goldilocks of fast lifts and big passes with throwback bonhomie undented?
Why you should ski Mammoth and June
If you live in Southern California, go ahead and skip this section, because of course you’ve already skied Mammoth a thousand times, and so has everyone you know, and it will shock you to learn that there is anyone, anywhere, who has never skied this human wildlife park.
But for anyone who’s not in Southern California, Mammoth is remote and inconvenient. It is among the least-accessible big mountains in the country. It lacks the interstate adjacency of Tahoe, the Wasatch, and Colorado; the modernized airports funneling skiers into Big Sky and Jackson and Sun Valley (though this is changing); the cultural cachet that overcomes backwater addresses for Aspen and Telluride. Going to Mammoth, for anyone who can’t point north on 395, just doesn’t seem worth the hassle.
It is worth the hassle. The raw statistical profile validates this. Big vert, big acreage, big snows, and big lift networks always justify the journey, even if Mammoth’s remoteness fails to translate to emptiness in the way it does at, say, Taos or Revelstoke. But there is something to being Not Tahoe, a Sierra Nevada monster throwing off its own gravity rather than orbiting a mother lake with a dozen equals. Lacking the proximity to leave some things to more capable competitors, the way Tahoe resorts cede parks to Boreal or Northstar, or radness to Palisades and Kirkwood, Mammoth is compelled to offer an EveryBro mix of parks and cliffs and groomers and trees and bumps. It’s a motley, magnificent scene, singular and electric, the sort of place that makes all realms beyond feel like a mirage.
Mammoth does have one satellite, of course, and June Mountain fills the mothership’s families-with-kids gap. Unlike Mammoth, June lets you use the carpet without an instructor. Kids 12 and under ski free. June is less crowded, less vodka-Red Bull, less California. And while the dated lifts can puzzle the Ikon tote-bagger who’s last seven trips were through the detachable kingdoms of Utah and Colorado, there is a certain thrill to riding a chairlift that tugged its first passengers uphill during the Eisenhower administration.
Podcast Notes
On Mammoth’s masterplan
On Alterra pumping “a ton of money into its mountains”
Tripling the size of Deer Valley. A massive terrain expansion and transformative infill gondola at Steamboat. The fusing of Palisades Tahoe’s two sides to create America’s second-largest interconnected ski area. New six-packs at Big Bear, Mammoth, Winter Park, and Solitude. Alterra is not messing around, as the Vail-Slayer continues to add mountains, add partners, and transform its portfolio of once-tired giants into dazzling modern megaresorts with billions in investment.
On D-Line lifts “floating over the horizon”
I mean just look at these things (Loon’s Kancamagus eight on opening day, December 10, 2021 – video by Stuart Winchester):
On severe accidents on Yan detachables
In 2023, I wrote about Yan’s detachable lift hellstorm:
Cohee referenced a conversation he’d had with “Yan Kunczynski,” saying that, “obviously he had his issues.” If it’s not obvious to the listener, here’s what he was talking about: Kuncyznski founded Yan chairlifts in 1965. They were sound lifts, and the company built hundreds, many of which are still in operation today. However. Yan’s high-speed lifts turned out to be death traps. Two people died in a 1985 accident at Keystone. A 9-year-old died in a 1993 accident at Sierra-at-Tahoe (then known as Sierra Ski Ranch). Two more died at Whistler in 1995. This is why all three detachable quads at Sierra-at-Tahoe date to 1996 – the mountain ripped out all three Yan machines following the accident, even though the oldest dated only to 1989.
Several Yan high-speed detachables still run, but they have been heavily modified and retrofit. Superstar Express at Killington, for example, was “retrofitted with new Poma grips and sheaves as well as terminal modifications in 1994,” according to Lift Blog. In total, 15 ski areas, including Sun Valley, Schweitzer, Mount Snow, Mammoth, and Palisades Tahoe spent millions upgrading or replacing Yan detachable quads. The company ceased operations in 2001.
Since that writing, many of those Yan detachables have met the scrapyard:
* Killington will replace Superstar Express with a Doppelmayr six-pack this summer.
* Sun Valley removed two of their Yan detachables – Greyhawk and Challenger – in 2023, and replaced them with a single Doppelmayr high-speed six-pack.
* Sun Valley then replaced the Seattle Ridge Yan high-speed quad with a Doppelmayr six-pack in 2024.
* Mammoth has replaced both of its Yan high-speed quads – Canyon and Broadway – with Doppelmayr D-line six-packs.
* Though I didn’t mention Sunday River above, it’s worth noting that the mountain ripped out its Barker Yan detachable quad in 2023 for a D-Line Doppelmayr bubble sixer.
I’m not sure how many of these Yan-detach jalopies remain. Sun Valley still runs four; June, two; and Schweitzer, Mount Snow, and Killington one apiece. There are probably others.
On Mammoth’s aging lift fleet
Mammoth’s lift system is widely considered one of the best designed anywhere, and I have no doubt that it’s well cared for. Still, it is a garage filled with as many classic cars as sparkling-off-the-assembly-line Aston Martins. Seventeen of the mountain’s 24 aerial lifts were constructed before the turn of the century; 10 of those are Yan fixed- grips, the oldest dating to 1969. Per Lift Blog:
On Rusty’s tribute to Dave McCoy
Former Alterra CEO Rusty Gregory delivered an incredible encomium to Mammoth founder Dave McCoy on this podcast four years ago [18:08]:
The audio here is jacked up in 45 different ways. I suppose I can admit now that this was because whatever broke-ass microphone I was using at the time sounded as though it had filtered my audio through a dying air-conditioner. So I had to re-record my questions (I could make out the audio well enough to just repeat what I had said during our actual chat), making the conversation sound like something I had created by going on Open AI and typing “create a podcast where it sounds like I interviewed Rusty Gregory.” Now I probably would have just asked to re-record it, but at the time I just felt lucky to get the interview and so I stapled together this bootleg track that sounds like something Eminem would have sold from the trunk of his Chevy Celebrity in 1994.
More good McCoy stuff here and in the videos below:
On Mammoth buying Bear and Snow Summit
Rusty also broke down Mammoth’s acquisition of Bear Mountain and Snow Summit in that pod, at the 29:18 mark.
On Mammoth super parks
When I was a kid watching the Road Runner dominate Wile E. Coyote in zip-fall-splat canyon hijinks, I assumed it was the fanciful product of some lunatic’s imagination. But now I understand that the whole serial was just an animation of Mammoth Superparks:
I mean can you tell the difference?
I’m admittedly impressed with the coyote’s standing turnaround technique with the roller skis.
On Pico beside Killington
The Pico-Killington dilemma echoes that of June-Mammoth, in which an otherwise good mountain looks like a less-good mountain because it sits next door to a really great mountain. As I wrote in 2023:
Pico is funny. If it were anywhere else other than exactly next door to the largest ski area in New England, Pico might be a major ski area. Its 468 acres would make it the largest ski area in New Hampshire. A 2,000-foot vertical drop is impressive anywhere. The mountain has two high-speed lifts. And, by the way, knockout terrain. There is only one place in the Killington complex where you can run 2,000 vertical feet of steep terrain: Pico.
On the old funitel at June
Compounding the weirdness of J1’s continued existence is the fact that, from 1986 to ’96, a 20-passenger funitels ran on a parallel line:
Clark explains why June removed this lift in the podcast.
On kids under 12 skiing free at June
This is pretty amazing – per June’s website:
The free June Mountain Kids Season Pass gives your children under 12 unlimited access to June Mountain all season long. This replaces day tickets for kids, which are no longer offered. Everyone in your family must have a season pass or lift ticket. Your child's free season pass must be reserved in advance, and picked up in-person at the June Mountain Ticket Office. If your child has a birthday in our system that states they are older than 12 years of age, we will require proof of age to sell you a 12 and under season pass.
I clarified with June officials that adults are not required to buy a season pass or lift ticket in order for their children to qualify for the free season pass.
While it is unlikely that I will make it to June this winter, I signed my 8-year-old son up for a free season pass just to see how easy it was. It took about 12 seconds (he was already in Alterra’s system, saving some time).
On Alterra’s whiplash Ikon Pass access
Alterra has consistently adjusted Ikon Pass access to meter volume and appease its partner mountains:
On Mammoth’s mammoth snowfalls
Mammoth’s annual snowfalls tend to mirror the boom-bust cycles of Tahoe, with big winters burying the Statue of Liberty (715 inches at the base over the 2022-23 winter), and others underperforming the Catskills (94 inches in the winter of 1976-77). Here are the mountain’s official year-by-year and month-by-month tallies.
