Dial Your Kit and Prepare for the Corn Harvest: An Essential Guide to Backcountry Spring Skiing

It might sound like heresy to diehards, but nearly all of my favorite ski days of the last decade have been during the spring. Sure, midwinter powder turns are fun, but the spoils — and occasional undernose sunburn — of mid-April and May ski days stick with me much longer.

Climbing to the top of a remote peak, waiting for the snow to flip to corn, and making buttery turns back to the car is a borderline religious experience, complete with challenges, thrills, and a lingering sense of accomplishment. Living in Oregon’s Cascades, spring is widely synonymous with volcano season, but there are great spring turns to be had in the Sierra, Tetons, Wasatch, Rockies, and elsewhere, too.

For context, I ski about 70 days each year, from December to June. This fluctuates a lot with the weather. I’ll sometimes make turns for a week straight during a big storm cycle, and then take a week off if conditions are sub-par. During winters like this one, which has been historically dry across the West, including where I live, I’ve turned most of my focus (and hope) toward the spring.

Even with a lower-than-normal snowpack, I’m optimistic that we’ll get a couple of solid months of corn harvesting.

To make the most of whatever we get, I’m planning ahead, waxing skis, checking gear, and practicing skills. As I go through my checklist, I want to share my best practices, in hopes it’ll encourage others to find the same joy.

Consider this your backcountry spring skiing 101.

Backcountry Spring Skiing Essentials

The Science of Corn

Before getting into safety, skills, and gear details, it’s important to start with the thermodynamics of the melt-freeze cycle.

During the spring, snow goes through a cyclical transformation from night to day and back. Overnight, liquid water on the snow surface freezes, bonding it into a hard, icy crust. In the morning, rising temps and solar rays break these bonds, releasing tiny balls of snow, which we lovingly call corn. This smooth and supportive surface is the holy grail of spring skiing.

The window for corn skiing isn’t an exact time; it’s determined by a complex formula of the aspect, sun, clouds, wind, and temperature. On an ideal spring ski morning, temps rise well above freezing, changing the top inch or two into corn. As the temperature rises throughout the day, the water content increases, and the snow turns to mashed potatoes. This has a suction effect on skis, which comes with risks.

The one part of the formula you can control is the aspect. Because the sun moves from east to west, eastern slopes will flip to corn first. If you follow the sun in a clockwise direction, you’ll maximize the number of turns you can get in a single day.

Understanding this aspect clock is one of the most important skills to learn for spring skiing, helping you find good turns and keep you out of trouble.

Hazards, Safety, and Strategy

Wet Slides

Staying too late comes with risks. Most types of avalanche problems — storm, slab, persistent layers — have resolved themselves by the spring. However, wet slides become more common, especially in the afternoon. As the sun warms the snowpack, water percolates downward and breaks the bonds that hold the slope together. This increases the mass and decreases the strength, eventually leading to wet slides.

To safely navigate slopes, keep an eye out for roller balls (accumulated snowballs that have rolled downhill and gathered mass). These indicate the snowpack is becoming, or has already become, dangerous.

If you don’t see roller balls but you’re unsure about the snowpack stability, you can test the same thing by rolling your own snowball downhill. If it picks up mass, it’s time to bail.

Rockfall

Rockfall is also more common as the day heats up. As ice melts, it relinquishes its grip on frozen rocks, which can then roll, tumble, or fall downhill. If you see or hear rocks falling, this is another clear sign you need to leave.

Ice

Another risk is slick, icy slopes, which you can manage with specific tools. In the early morning, if your skins slip on the surface below you, it’s time to switch to ski crampons. Ideally, you put them on before needing them, because it’s hard to transition on a slippery slope.

If it’s too steep for ski crampons, switch to regular crampons and bootpack upward. Use your toes to kick steps into the snow, while keeping multiple points of contact with the ground using your poles and ice axe.

Steep Pitches

Spring skiing often takes you to steeper pitches, where it’s helpful to know how to jump turn. The easiest way is to plant your pole and use it as a pivot point, jump vertically, and then rotate your skis in the air. This timing and movement take practice, which is best done on low-angle slopes.

Heavy Snow

Last but not least, knee injuries from heavy, sticky snow are common, especially later in the day when the snow is heavy and you are tired. Remember that the snow lower down the mountain is usually warmer and stickier.

Specialized Gear

Like all endeavors in the mountains, having the right kind of gear and going prepared makes an enormous difference in both enjoyment and safety.

However, spring demands a different kit than midwinter powder days, focused on breathability, less weight, and tools for ice and sun. Here are my top suggestions for spring tours.

Spring Skis

At least in the PNW, spring skiing often involves a lot of vertical. The high volcanoes rise more than 7,000 feet above the trailhead, which means you need to be conscious of weight. However, ultralight skis usually mean less confidence on steep, technical lines, so I prefer something that sits in the middle. A good spring ski is one I can haul to the top of a peak without being exhausted, but one I can also fully trust on the descent.

Another factor is underfoot width, with narrower skis having a tighter turn radius, more agility, and a better grip on icy slopes. However, they also offer less rigidity or the ability to handle heavy slush, as you’ll see in the afternoon.

For my absolute biggest days, I use the Elan Ripstick Tour 94, which weighs in at 1,300 g and is still fun to ski on most objectives and snow. For the more technical descents, I rely on the Renoun Endurance 98 to get me down safely. It has damping technology and a much stiffer edge hold, which helps me to ski harder and faster in mixed conditions, tight couloirs, and on steeper faces.

Bindings & Boots

Like picking the right spring ski, the perfect binding is a balance between performance and weight.

My current go-to is the ATK Raider 11 EVO, which has a number of features that put it ahead of the pack, while weighing in at just 370 g. The heel piece can be flipped between uphill and ski mode with just one hand. Magnetic risers are easy to flip with a pole basket. Most importantly, the EVO system provides built-in elasticity that makes the Raider feel like a resort binding.

Your boots also have to strike this balance between uphill efficiency and downhill precision. I use the Dynafit Ridge Pro, thanks to its insane weight-to-power ratio. They weigh just 1,250 g while offering a progressive, stiff flex that feels like a race boot. The floating tongue ensures a snug fit and reduces blisters, and the 70-degree flex makes it more comfortable to tour with.

Finally, the Hoji lock system makes transitions easy with a simple flip in the back of the boot, so you’re ready when the corn flips.

Skins & Sharps

A key component of spring skiing is the icy slopes in the early morning, which are challenging to ski but climbable with the right tools and know-how. I rely on Pomoca Tour Pro Skins, which are grippy for icy mornings, while also anti-glopping for hot afternoons and sticky snow.

I also carry skin wax for all of my spring tours, which mitigates sticking to my skins. There are a lot of brands out there. Swix, Pomoca, and mountainFLOW all make their own versions.

If I feel like my skins aren’t providing enough traction, I’ll throw on Dynafit Ski Crampons. They slide into the toe piece of the binding and bite the snow as I step down, which makes them super-easy to use. Just remember not to have your heel risers on, or they lose most of their efficacy.

On the steepest slopes, when the skis have to be carried, I bootpack using Petzl Irvis Hybrid Crampons. With practice, putting them on takes mere seconds thanks to the rear lever lock system. The front half is steel, meaning it’s durable enough to climb on rocks, and the Dyneema connection allows them to pack down much smaller than most crampons.

The Petzl Ride Ice Axe completes my spring ski kit and helps make me feel comfortable in spicy spots. The Ride is a lightweight 240 g with a fully tempered steel head, providing the same self-arrest ability as a larger axe. The length works great on steep pitches, while being easy to stow away. Combined, skins, ski crampons, hybrid crampons, and an ice axe all fit into my pack, making it safer to climb and descend steep lines.

Helmet & Sun Protection

Spring days are often defined by quick temperature swings, intense alpine sun, and high-output efforts. Therefore, you want a helmet that breathes well, sunglasses that protect your eyes, and sunscreen with zinc, which acts as a physical barrier between your skin and the sun. In high-altitude environments, UV radiation is more intense, so you need to take extra measures to protect yourself.

My go-to helmet is the Mammut Haute Route Twiceme, which is dual-certified for skiing and mountaineering. Unlike resort helmets that can feel like an oven on a long skin track, the Haute Route has extensive venting to dump heat, is ultralight, and has integrated MIPS technology that protects you against rotational impacts and rockfall, which is common on many spring days.

I pair it with the Julbo Shield Sunglasses, which solve the goggle fog dilemma. These provide enough coverage to keep my eyes from watering, even when skiing fast. The Shield blocks lateral glare to protect my eyes on glaciers, and is equipped with Reactiv photochromic lenses that go up to Cat 4, the darkest tint possible, keeping my eyeballs safe even on the brightest days.

Baselayers & Shells

In the spring, layering shifts away from insulation toward breathability, sun protection, and wicking materials. I use the Patagonia Capaline Cool Sun Hoody on most tours, which traps just enough warmth while allowing most of the moisture to escape as my heart rate climbs. The hood is great for protecting my ears and neck from the sun and is quick-drying, perfect for long days as the temperature fluctuates.

On top of that, I prefer softshell jackets because they breathe much better than midwinter hardshells, so I don’t sweat through all my layers. My favorite is the Patagonia Upstride Jacket, which is stretchy, cuts the wind, repels light snow, and packs down for easy stowing. Together, they provide a streamlined system that saves me a lot of time, keeping me warm on the ascent and comfortable on the descent.

Bonus: Keep It Weird!

The biggest sin of spring skiing — at least as far as I’m concerned — is taking yourself too seriously. Remember, we’re all out here for the same reason: to soak up rays, make squiggles, and have as much fun as possible. Sometimes that means bringing a few extra things to make sure you’re keeping it weird.

I suggest a bucket hat, or even better, an Outdoor Research Papyrus Sun Hat, or just about anything from Fractel Hats. Pair that with a Patagonia Hawaiian Shirt or one of Party Shirt International’s button-downs, so that everyone knows your vibe.

Once you finish skiing for the day, it’s always nice to have a YETI Cooler filled with ice and cold bevvies waiting for you at the truck. And, preferably, a Primus Double Burner camp stove to fry up some brats and burgers on the tailgate as well. A few NEMO Camp Chairs always come in handy to take a load off and soak up the moment with friends.
