Give Michelangelo some marble, and you’ll probably get a sculpture. Give him some late-spring snow and a snowcat, and he might be Mammoth Mountain’s Director of Slope Maintenance and the Unbound Terrain Parks, Scott Cherry.
Cherry organizes the resort crews who keep Mammoth and its terrain parks open long after other ski areas have shut down and transitioned to summer activities. This is because Mammoth is not like other ski areas. Most ski areas don’t consistently build terrain parks and maintain ski trails until the end of May.
Mammoth plans to keep lifts spinning as late as possible. From the end of April until that fervent closing day, resort crews will give every nail, tooth, and tear they have left in an effort to keep the mountain open and the runs skiable. They do a damn good job. Snowcats will push, pull, extract, and chisel snow off some slopes and onto others in a process that Mammoth refers to as “snow farming.” It’s like sculpting, but in accordance with nature and on a very large scale with very large machinery. Even airborne tools—strapped onto airplanes—get used in the mountain’s unique snow farming system.
“The one thing we have on our side that’s a game-changer is SNOWsat, which is basically sonar with lidar mapping of our mountain,” Cherry said over the phone. “So they’ll fly a plane over our mountain, map it for us, and then upload it onto their system and create layers. Then they’ll upload that layering onto a tablet-sized screen inside the snowcats which will tell you within a half-an-inch of where your snow’s at. It’s like a fishfinder.”
The technology described by Cherry is not controlled by him and his team but rather by PistenBully, which is contracted with Mammoth. With the use of lidar, cat drivers can see exactly where the snow is—and precisely how much of it is left—on a screen inside the snowcat. Cherry can simultaneously look at another map on his computer screen that shows exactly where every cat has gone and moved snow, and what terrain features are still untouched.
“It’s an ongoing, developing technology. But it’s extremely accurate. It’s awesome,” Cherry said.
Six of Mammoth’s snowcats are equipped with this software. With digital maps displayed on screens inside the cats, Cherry and his drivers use that information in a way that mimics chess. They observe, contemplate, and strategize which slopes will still hold snow and for how long. Cherry and his team can forecast snow conditions weeks in advance, so it becomes clear which slopes won’t make it. The slopes that are the next to go, Cherry and his team decide, are the ones that drivers will take snow from and redistribute towards those that will still provide decent Spring skiing. It’s challenging work, according to Cherry, and slopes with minimal snow get abandoned all the time—their organs are getting transplanted to other, healthier parts of the mountain.
Which is when the magic happens. Snowcat operators will show up at 3 in the afternoon (when the snow is soft from the sun’s heat) and work until midnight, before the mountain temperatures harden it into firm, fast-skiing snow. They’ll follow the lidar maps on their screens and go to the exact pinpoint of snow that needs to be moved. They’ll farm that snow, push it out at night, and then groom it. But the way they farm it is where the process gets especially interesting.
Cherry describes the snow farming process as “typewriter-ing.” It starts with finding dirt. Snowcat operators grooming at night will relay to Cherry which slopes are hurting and which need more snow, and then Cherry will go out in a snowcat, typically the next morning, and farm snow for the drivers to shuffle around. He starts on a slope with both movable snow and dirt. This allows him to move the snow much more efficiently than if the snow were sitting on more snow. Working from the top down, Cherry will go back and forth—like he’s driving his cat along the lines of a typewriter’s keyboard—gathering more snow and dirt as he descends each row. By the time he gets to the bottom, he may have a pile of farmed snow that’s 30 feet high or higher.
“The better we are at farming the longer we’re able to hold onto our season,” Cherry said.
This blend of science and art—which allows one to move around snow as their mind sees fit—also comes into play with Mammoth’s Unbound terrain parks. Cherry said that it’s rare to see terrain parks open at ski areas this late into the Spring—let alone ones of Mammoth’s caliber with giant jumps and complex jib features. And only a handful of ski areas still showcase 60 or 70-foot jumps every season.
With a background in building terrain parks, Cherry’s career eventually led him to Mammoth, where he got to maximize his potential. When it comes to building a massive park or working with specifics for slopestyle events like Red Bull Recharged, Cherry and his crew will sometimes have to farm snow for 14 days before they can begin sculpting certain features. It takes lasting commitment and astute attention to detail to build Mammoth’s competition-grade features and terrain parks, which may not necessarily be noticeable at first glance when watching these competitions on YouTube.
“When you see those guys enjoy the product that you’ve spent every waking moment trying to get right, that makes it all worth it,” Cherry said.
Scott Cherry loves his job, and it shows. How else would Mammoth swindle Mother Nature into staying open for skiing and riding until August?
