Mount Chimborazo stands 20,564 feet above sea level. Everest rises to 29,032 feet.
By that standard, it’s no contest. But there’s another way to measure a mountain’s height — the distance from Earth’s center to its summit — and by that reckoning, Everest comes up short.
The summit of Chimborazo sits 3,967 miles from Earth’s core. Everest’s summit sits 3,966 miles away.
That difference of roughly a mile and a quarter is enough to make this Andean volcano — sitting just one degree south of the equator — the farthest point on Earth’s surface from the planet’s center.
That makes it the closest point on Earth to outer space.
Why a Shorter Mountain Can Be Farther From Space
The answer lies in the true shape of the Earth.
The planet is not a perfect sphere. It bulges at the equator and flattens at the poles — a distortion caused by its rotation.
That equatorial bulge means the surface near the equator already sits several miles farther from the core than at mid-latitudes or the poles, before any mountain adds so much as a foot.
Chimborazo happens to sit almost directly atop that bulge, just one degree from the equator.
Everest, by contrast, rises at 28 degrees north latitude, where the planet’s curvature has already reduced the distance to the core. Despite its towering elevation above sea level, its position on the globe works against it here.
GPS measurements by the Third French Geodesic Expedition placed Chimborazo’s summit at 20,925,528 feet from Earth’s core, compared to 20,918,438 feet for Everest.
Put simply: anyone standing on Chimborazo’s summit is closer to outer space than anyone else on Earth — including those at the top of Everest.
A Mountain That Was “the Highest in the World” for Centuries
Before the systematic exploration of the Himalayas revealed the true scale of its peaks, Chimborazo was considered for centuries the highest mountain on Earth.
That reputation drew explorers, scientists, and mountaineers from the 17th century onward, establishing the Ecuadorian volcano as one of the great prizes of European scientific ambition.
Its most famous visitor was Alexander von Humboldt, who in 1802 attempted to reach the summit alongside Aimé Bonpland and the Ecuadorian-born Carlos Montúfar.
They turned back at 19,275 feet due to altitude sickness — but at that point, Humboldt had climbed higher than any human on record.
The expedition yielded one of his most enduring scientific insights: he observed that bands of vegetation reappeared at equivalent altitudes on different mountains around the world, laying the foundations of what would become altitude ecology.
The first successful ascent came decades later, on Jan. 4, 1880, when British alpinist Edward Whymper reached the top alongside Italian guides Louis and Jean-Antoine Carrel.
Their legacy survives on the mountain: the two refuges marking the approach to the summit are named after the men who pioneered the route.
What You Find on the Slopes Before Reaching the Glacier
The Chimborazo Fauna Production Reserve, established in 1987 and covering more than 143,000 acres, wraps the volcano in a high-altitude páramo ecosystem that has little in common with the barren, windswept image most people associate with snowcapped peaks.
On the road toward the refuges, above 13,000 feet, vicuñas cross the dirt track often enough that you stop noticing them. Chimborazo is the only place in Ecuador where the species exists.
Andean condors, with wingspans of up to nearly 10 feet, ride the thermal currents that rise along the volcanic slopes. The Chimborazo hillstar hummingbird — one of the few hummingbirds in the world capable of surviving above 9,800 feet — turns up with surprising regularity near the Hermanos Carrel refuge at 15,912 feet.
The high-altitude flora includes the chuquiragua, a frost-resistant orange-yellow flower that has become an emblem of the Ecuadorian páramo.
The Ice Harvesters: A Trade That Lasted Centuries and Died in 2024
Chimborazo has a parallel story that has little to do with mountaineering and everything to do with the life sustained at its base.
For generations, indigenous communities in the area climbed the volcano every Tuesday and Friday to cut blocks of ice from the glaciers with picks and shovels. They wrapped the blocks in straw, loaded them onto mules, and carried them down to the La Merced market in Riobamba, where they were sold to make juices and shaved ice.
In Quechua, Chimborazo is the taita — the father — and drinking water from its glaciers carried a ritual significance that, for these communities, was as sacred as the Catholic Mass itself.
At the height of the tradition, as many as 40 ice harvesters worked the mountain.
With the arrival of industrial refrigeration, the trade slowly dwindled until it rested in the hands of a single man: Baltazar Ushca. Known throughout Ecuador as the last ice harvester of Chimborazo, he kept the tradition alive for more than six decades, climbing the volcano twice a week.
He died in October 2024, taking the trade with him. But the Carlos Zambrano glacier, from which he harvested his ice, remains — shrinking each year, eaten away by rising temperatures and by ash from the Tungurahua volcano, which darkens the snow’s surface and speeds the glacier’s retreat.
The silhouette of Chimborazo — sacred mountain and centerpiece of Humboldt’s maps — appears at the center of Ecuador’s national coat of arms.
This is Chimborazo: a mountain once considered the highest in the world, now known to be the closest point on Earth to outer space, and home to a story of ice, faith, and high-altitude wilderness that no geodesic survey can fully capture.
