Comparing North America’s Highest Peaks, Denali vs. Mount St. Elias—Goliaths of the North

High above Alaska’s sweeping, expansive wilderness, Mount McKinley (also known as Denali) and Mount St. Elias rise with a presence rarely found anywhere else on Earth that commands both attention and a deep respect. Both are awe-inspiring in their own stature—Denali, tucked deep within the continent’s interior, and St. Elias, towering abruptly from sea to summit in just a matter of miles.

Height vs. Relief 

Mount McKinley (Denali) reaches 20,310 feet with a prominence of 20,157 feet, making it North America’s highest summit. Its massive bulk creates some of the greatest base-to-summit relief on any mountain on Earth. Mount St. Elias, though sits slightly lower at 18,008 feet and delivers something unique: it has nearly 18,000 feet of continuous vertical rise from tidewater—a sea-to-summit profile unlike almost anywhere else on the planet. Its prominence stands at 11,250 feet.

Weather and Latitude

Mount McKinley’s interior position at 63°N latitude makes it the most northerly major peak over 20,000 feet. Here, the cold is downright relentless. At 15,000 feet, a thermometer once recorded a temperature of –100°F (–73°C). Snow is possible in every month of the year, a reminder that Denali’s weather operates on its own unforgiving terms. Mount St. Elias at 60.2933° N, though slightly farther south, exchanges Arctic cold for coastal volatility. Storms roar in from the Gulf of Alaska, cloaking the peak in ice and avalanches, while the mountain itself shoulders some of the largest icefields outside the polar regions.

Ice and Power

Mount McKinley holds vast glaciers pouring down from its slopes. Still, Mount St. Elias is a gateway to something even larger: the Malaspina and Bagley Icefields, sprawling frozen seas that dwarf entire states. If Mount McKinley embodies the cold endurance of the sub-Arctic, Mount St. Elias manifests the restless weight of ice at the ocean’s edge.

Two Ways to Dominate

So which mountain is the more difficult climb? That depends on altitude tolerance, remoteness, weather, willpower, and grit. But the comparison reveals a deeper truth: Mount McKinley and Mount St. Elias represent two archetypes of mountains. One rises from the continent’s heart, demanding resilience against altitude and cold. The other surges skyward from tidewater, reminding us of the raw power where land meets sea.

To bring this full circle, one has to wonder what the number of successful climbers who reach the summit of Mount McKinley is? Out of ~1,000 climbers, roughly 35% reached the summit this season. Mount. St Elias proved difficult to trace any reliable climbing data. This could suggest that St. Elias is more difficult to climb.

In their own ways, both mountains ask the same question: What does it mean to rise against insurmountable odds?
