Mountain Picker

Which peak will the climber reach?

Peaks on the skyline

Tap a mountain to keep it in the draw — all 20 fit at once, and you can add your own.

Choose which peaks are on the skyline, then send the climber out. Every mountain is drawn to true relative scale against the metre axis, so you can see exactly how they compare while the climber walks the ridge and stops on one.

Random Mountain Picker

A random mountain, picked on a skyline drawn to scale

The Mountain Picker chooses one of twenty famous peaks at random — but instead of spinning a wheel at a list of names, you send a climber walking along a cross-section of the world. Every mountain on that skyline is drawn to its true height against a metre axis, so Everest towers and Table Mountain sits low, exactly as they do on Earth. The climber walks the ridge, slows, and tops out on one summit.

How it works

Choose the peaks

Tap the mountains you want on the skyline. All twenty fit at once, or narrow it to the shortlist you are actually choosing between.

Send the climber

Press the button. The climber sets off from the left and walks the ridge line itself, up one flank and down the other, with the camera panning alongside.

Read the scale on the way

The metre axis stays fixed at the left of the frame while the landscape scrolls past, so you can read any summit's height off the gridlines as you go.

The climber tops out

The walk decelerates and stops on one peak. A flag plants on the summit and a dashed line measures its altitude back to the axis.

Take the result

A plate drops in with the full name, the elevation and the range, and the answer stays on the page — no popup unless you ask for one.

The twenty peaks, and how they measure up

A name on its own is a shrug — "you got the Eiger" means more once you know it is only the fourteenth-tallest here but carries the most feared face in the Alps. Every result comes with its elevation, its range and a line on why it matters.

Mountain	Elevation	Range / country	Why it's here
Everest	8,849 m	Himalaya · Nepal–China	The highest point on Earth; its summit sits in the jet stream.
K2	8,611 m	Karakoram · Pakistan–China	Second highest and far harder — a steep pyramid of rock and ice.
Kangchenjunga	8,586 m	Himalaya · Nepal–India	Third highest, five summits wide, and sacred to the valleys below.
Aconcagua	6,961 m	Andes · Argentina	The roof of the Americas, and walkable without ropes.
Denali	6,190 m	Alaska Range · United States	Rises further from its own base than almost any mountain on Earth.
Kilimanjaro	5,895 m	Tanzania	A free-standing volcano straight off the African plain.
Elbrus	5,642 m	Caucasus · Russia	Europe's highest point — a twin-coned dormant volcano.
Popocatépetl	5,393 m	Mexico	An active volcano smoking in plain sight of Mexico City.
Mount Ararat	5,137 m	Turkey	A lone snow cone on the plain, visible a hundred kilometres away.
Vinson Massif	4,892 m	Sentinel Range · Antarctica	Antarctica's highest, 1,200 km from the South Pole.
Mont Blanc	4,808 m	Alps · France–Italy	The white dome where mountaineering began, in 1786.
Matterhorn	4,478 m	Alps · Switzerland–Italy	A four-sided horn carved by four glaciers; the most photographed peak anywhere.
Mount Rainier	4,392 m	Cascades · United States	More permanent ice than any other peak in the lower 48.
Eiger	3,967 m	Bernese Alps · Switzerland	Modest in height, notorious for its 1,800 m north face.
Mount Fuji	3,776 m	Japan	An almost perfectly symmetrical volcano and a national symbol.
Mount Etna	3,357 m	Sicily · Italy	Europe's most active volcano — it changes its own height.
Mount Olympus	2,917 m	Greece	Greece's highest, and the address the ancients gave their gods.
Mount Kosciuszko	2,228 m	Australia	The gentlest Seven Summit — a rounded whaleback with a path.
Ben Nevis	1,345 m	Scotland	Britain's highest; in cloud roughly three days in four.
Table Mountain	1,085 m	South Africa	A three-kilometre flat top, far older than the Himalaya.

Why the heights are drawn to scale

Most random pickers flatten their options into identical slots. That is fine for pizza toppings and hopeless for mountains, because the whole interest of a mountain is a number you cannot really picture. "Kilimanjaro is 5,895 m" means nothing until it is standing next to Ben Nevis at 1,345 m and you can see it is more than four of them stacked up.

So the stage plots every selected peak on one shared scale, against a fixed axis marked every 2,000 m. The axis does not scroll with the landscape — it stays pinned to the left of the frame while the terrain slides past, which means the measurement is readable at every moment of the walk rather than only at the end.

A side effect worth noticing: switch off the three eight-thousanders and the whole skyline re-scales around Aconcagua. The picker is not just choosing for you — it is a small comparison tool you can drive.

Why a climber on a ridge, not a spinning wheel

A spinning wheel is a pointer travelling a closed loop with the options sitting on that loop. It is a fine mechanism and it is used everywhere on this site — but it tells you nothing about what it is choosing between. Here the path is an open line: the climber starts at one end of the range and walks to wherever the draw has landed, so every candidate is something you pass rather than something that flicks by.

It also makes the result feel earned. A wheel stops; a climber arrives. The peak is reached, a flag goes in, and the altitude is measured off the axis — which is roughly what actually happens on a first ascent, minus the frostbite.

The Seven Summits, all present

The Seven Summits — the highest peak on each continent — is the most-attempted list in mountaineering, and all of them are on this skyline: Everest (Asia), Aconcagua (South America), Denali (North America), Kilimanjaro (Africa), Elbrus (Europe), Vinson (Antarctica) and Kosciuszko (Australia).

They are also wildly unequal, which is exactly why they look good on a scale drawing. Kosciuszko is a signposted walk you can do in an afternoon; Vinson needs a chartered flight to a blue-ice runway; Everest needs a season. Switch the other thirteen peaks off and the picker becomes a Seven Summits randomiser on its own.

Reading a mountain's height honestly

Elevation — height above sea level — is what this picker plots, and it is what nearly every "highest mountain" list means. It is not the only honest measurement, though, and the alternatives produce different winners:

Rise from base. Denali climbs about 5,500 m from the plateau it stands on. Everest starts from a plateau already 5,000 m up, so it only rises around 3,700 m from its base camp.
Distance from the centre of the Earth. The planet bulges at the equator, so Chimborazo in Ecuador — a mere 6,263 m by elevation — is the point on the surface farthest from the core.
Measured from the seabed. Mauna Kea in Hawaii is over 10,000 m tall from its underwater base; only 4,207 m of it is above water.
Prominence. How far you must descend before you can climb something higher. It is why Mont Blanc dominates the Alps even though several Himalayan peaks are far taller.

None of these is a trick answer. They are four different questions, and "which mountain is biggest" quietly picks one without telling you.

Ways to use the Mountain Picker

In a geography lesson

Draw a peak per pupil for a short research task, or put it on the board and let the to-scale skyline do the explaining before anyone writes a number down.

For a trivia round

Pull a random mountain and ask for the range, the country or the continent. The result plate carries the answer, so you can score it on the spot.

Planning a climb or a trek

Cut the list to the peaks actually within reach this year and let the draw settle an argument that has been going in circles.

As a writing prompt

One peak, one paragraph. The verdict line gives you a hook, and the elevation gives you something concrete to build on.

Add your own peak

The twenty built-in mountains are a starting point, not a limit. Type any peak into the box and it joins the skyline with the same odds as everything else — your local hill, the route you are training for, or a shortlist of three you cannot choose between. A custom peak has no published elevation, so the picker draws it at the median height of the current skyline rather than inventing a number; the scale stays honest and your own entry still gets a fair draw.

Mountain Picker FAQ

The winning mountain is drawn with your browser's cryptographic random generator before the climber takes a step, using rejection sampling so there is no remainder bias. The peaks are also shuffled into new positions along the skyline on every run, so no place on the ridge is ever favoured. Every mountain you leave switched on has exactly equal odds.

Twenty: Everest, K2, Kangchenjunga, Aconcagua, Denali, Kilimanjaro, Elbrus, Popocatépetl, Ararat, Vinson, Mont Blanc, the Matterhorn, Rainier, the Eiger, Fuji, Etna, Olympus, Kosciuszko, Ben Nevis and Table Mountain. That is the complete set of Seven Summits plus the most recognisable shapes in mountaineering, spread across every continent and from 1,085 m to 8,849 m.

Yes. Each peak's height on the stage is its elevation above sea level, plotted against the fixed metre axis on the left of the frame, on one shared scale. Everest really is drawn a little over eight times the height of Table Mountain, and the gridlines at 2,000 m intervals let you read any summit off directly.

Because a wheel throws away the one thing that makes mountains interesting — how they compare. Slices on a wheel are all the same size whether the peak is 1,000 m or 8,849 m. A cross-section keeps the real proportions, and the climber walking an open line across it lets you see every candidate on the way past. The random pick underneath is identical.

Not quite. Elevation is height above sea level, which is what this picker plots and what almost every list means by "highest". Measured from its own base, Denali rises further than Everest does; measured from the centre of the Earth, Chimborazo in Ecuador is the farthest point because the planet bulges at the equator; and measured from the seabed, Mauna Kea beats them all. Same rock, three different winners.

Yes. Type any peak into the "Add your own peak" box and it joins the skyline with exactly the same odds as everything else — useful for a local hill, a route you are planning, or a shortlist of your own. A custom peak has no published elevation, so it is drawn at the median height of the current skyline to keep the scale honest.

Yes, and it is the best way to use it. Tap off everything you are not considering and the draw runs on what is left — two peaks, three, or any shortlist. A picker is only useful when every option on it is one you would genuinely accept.
