Backcountry skiing, once a niche pursuit for dedicated alpinists and enthusiasts of vintage ski techniques, has surged into the mainstream, with trails once frequented by only a few now seeing a significant increase in participants. This burgeoning popularity culminates with ski mountaineering, or "skimo," making its debut at the 2026 Winter Olympics in Milan-Cortina, marking the first addition of a new sport to the Winter Games in nearly three decades. Skimo, born from the same rugged alpine terrain that draws so many away from ski lifts, will showcase the discipline’s blend of endurance and technical prowess on the world’s grandest stage.

The Olympic skimo competition will feature a select field of just 36 athletes, comprising 18 men and 18 women, who will contend across three medal events: men’s sprint, women’s sprint, and a mixed-gender relay. Competitors will navigate steep alpine ascents and descents using ultra-lightweight gear, employing climbing skins to ascend and then shedding them for rapid, technical descents. This inclusion in the Olympics, coupled with the broader surge in backcountry skiing, represents a significant moment for a segment of mountain culture that has long thrived outside the confines of commercial resorts. However, this ascent in popularity is shadowed by the growing threat of climate change, which is steadily eroding the very winter conditions that make this lifestyle possible.

The author, an avid backcountry skier who began their uphill journeys six years ago, reflects on the shift away from traditional resort skiing. The prohibitive costs of lift tickets and season passes, the congestion of holiday weekends, and the arduous traffic associated with popular ski destinations became increasingly deterrent. These factors, combined with a pandemic-induced desire for open spaces, pushed many, including the author, toward the allure of the backcountry. Prior to embracing backcountry skiing, the author discovered a passion for cross-country skiing, appreciating the ability to explore familiar hiking trails and snow-covered forest service roads in solitude, often accompanied by dogs and friends. This initial foray into touring eventually led to the need for more specialized equipment, paving the way for an introduction to backcountry skiing.

This personal journey mirrors a broader trend across the United States, where participation in backcountry skiing has seen remarkable growth. Industry data indicates a significant increase in "alpine touring," the technical discipline most closely associated with backcountry skiing, during the 2021-22 winter season, with splitboarding experiencing a similar sharp rise. These gains have notably outpaced the growth seen in traditional resort-based alpine skiing and snowboarding. The burgeoning popularity of backcountry skiing can be attributed to a confluence of factors: the development of more affordable and high-performing gear, a strengthening culture of skill-sharing and safety education, and a widespread desire for the open spaces and tranquility that commercial resorts often struggle to provide. Terrain and slopes that once felt exclusive are now accessible and familiar to a generation that came of age with social media and sought outdoor refuge during pandemic lockdowns.

Backcountry skiing, at its core, involves skiing beyond the boundaries of controlled ski resorts, venturing into ungroomed, unpatrolled, and un-lifited terrain. The primary draw is the promise of untouched snow, dynamic natural landscapes, and the satisfaction of "earning your turns"—the physical exertion of climbing uphill to then descend pristine, untracked runs. However, this freedom comes with inherent risks that the Olympic spotlight cannot diminish. Outside resort boundaries, there are no avalanche control measures, no ski patrols, and no marked hazards. Skiers are solely responsible for assessing terrain, evaluating snowpack stability, monitoring weather patterns, and making prudent decisions in unpredictable and often challenging conditions. Avalanche education and companion rescue training are not merely recommended; they are essential. Most experienced backcountry travelers undertake formal avalanche courses, diligently practice rescue drills with transceivers, probes, and shovels, and spend years developing an understanding of how wind, temperature fluctuations, and snow layers interact to create hidden dangers.

Despite extensive training, the margin for error in avalanche terrain remains razor-thin. Avalanches tragically claim dozens of lives in North America each winter, often affecting experienced backcountry users. Recent incidents, such as a significant avalanche in Lake Tahoe that trapped fifteen skiers, resulting in eight fatalities, underscore the persistent dangers. While the growth in backcountry participation has spurred increased education and awareness, it has also led to greater exposure to these risks. Every backcountry excursion involves a calculated negotiation with the inherent uncertainties of the mountain environment.

Ski mountaineering, as practiced in the Olympic format, involves athletes racing uphill sections on lightweight skis equipped with skins, occasionally transitioning to hiking, before removing the skins and descending as swiftly as possible. This discipline is a demanding fusion of endurance and technical downhill skiing, with roots tracing back to alpine military patrols of the early 20th century. The Olympic skimo events are designed for intense, immediate competition, with sprint races packing ascents and descents into minutes of explosive effort, and mixed relays challenging pairs of male and female athletes with speed and precision across alpine terrain. While the spectacle highlights extraordinary human athleticism, the author perceives this Olympic debut as a poignant moment, perhaps marking the beginning of an end for the very environment that nurtures this sport.

The profound irony and tragedy lie in the burgeoning love for these wild mountain landscapes precisely at a time when the climate that sustains them is undergoing rapid transformation. Climate change is no longer an abstract future threat; it is actively reshaping where and how winter is experienced, disrupting entire cultures and lifestyles. Projections from climate research institutions and the International Olympic Committee indicate a significant reduction in the number of locations worldwide capable of reliably hosting winter sports like skiing under current emissions trajectories. By the mid-2050s, a substantial proportion of existing Winter Olympic venues may fail to meet the necessary temperature and snow-reliability criteria for competition, drastically narrowing the pool of potential host cities.

The 2026 Milan-Cortina Games already exemplify this challenge, with artificial snow playing an indispensable role in staging the events. Extensive scaffolding of snowmaking machinery blankets competition slopes in northern Italy, a testament to the unreliability of natural snowfall. This technological workaround, however, demands considerable water and energy resources, starkly illustrating the precariousness of contemporary winter conditions. In the Western United States, communities that have long relied on consistent snowpack for tourism, water storage, and local economies are grappling with record-warm winters and severe snow droughts. Recent snow surveys in Colorado, Utah, and Oregon have documented historically low snowpack levels, with far-reaching consequences for water supplies, wildfire risk, and the outdoor recreation economy.

The ski industry, a significant economic force, continues to adapt. North America recorded over 61 million skier visits in the 2024-25 season, and resorts are investing heavily in year-round attractions such as alpine slides and zip lines, alongside infrastructure upgrades like new lifts and snowmaking systems. These investments represent a strategy to mitigate the impacts of an increasingly variable climate. Resorts are enhancing their reliance on snowmaking and comfort amenities, while the availability of natural powder snow becomes less predictable. While these adaptations may offer a temporary reprieve, they do not guarantee the continuation of winters as they have historically been known.

In the backcountry, the stakes are even more immediate and profound. Without snowguns or groomers, the experience is stripped down to its essence: skin tracks leading upward and the hope of untracked powder on the descent. This elemental connection is a significant part of the sport’s appeal, yet its very purity renders it vulnerable to a warming climate. Shorter snow seasons, an increase in rain-on-snow events that rapidly melt existing snowpack, and the degradation of ecosystems vital to winter sports all pose significant threats.

The author, writing from southwestern Colorado, reflects on the mountain landscapes that have defined so many of their winters and contributed significantly to their identity. The expectation of deep powder in February is replaced by unseasonably warm days, with temperatures in the 60s Fahrenheit. While winter is unlikely to vanish overnight, each warm season, each snow drought, and each ski resort’s increasing dependence on artificial snow contribute to a larger narrative of the season’s fragility. As backcountry skiing continues its growth trajectory and ski mountaineering solidifies its place on the Olympic stage, this expansion should evoke both excitement and a measure of unease. The future of this sport is inextricably linked not only to human endurance and passion but also to the climate that makes snow possible. The choices made today will determine whether future generations can continue to ascend above the treeline and descend into the profound wonder of a snow-covered mountain.
