Aiguille du Midi and Mont Blanc – Glaciers above Chamonix

September 2026. The cable car hauls you up out of Chamonix – first over forest, then over rock, then over nothing at all. 25 degrees below, zero at the top. 3,842 metres. The Aiguille du Midi is a granite needle on which someone very bravely put a station. Up there a sky so clear you think you can see to the end of the Alps. Peak after peak, ridge after ridge. Nothing in the way.

Opposite stands Mont Blanc, white and round like a freshly made bed. From its dome the Bossons Glacier tumbles down towards Les Bossons and Les Houches as if it had run out of patience: a huge field of ice, broken into seracs, crevasses and ribs. Its tongue reaches lower into the valley than any other in the Alps. From afar it looks smooth. Up close it is a jumble of blue, white and rubble – structures that rearrange themselves with every look.

At mid-height, the middle station, Plan de l’Aiguille. Get off, scree under my boots, a short hike. The needle above me, the glacier always in view, and suddenly very close.

Up top, the vastness. Down below, the force.

Crevassed glacier with blue ice in the Mont Blanc massif above Chamonix

An alpine glacier landscape unfolds above the Chamonix valley – ice, snow and rock ridges as far as the eye can see.
Mont Blanc and a broad glacier seen from the Aiguille du Midi, layered ranges behind
From the Aiguille du Midi the snow dome of Mont Blanc feeds a broad glacier that drops toward the Chamonix valley. Ogives, debris and bare ice, with layered ranges beyond.
Mont Blanc summit with a wind cloud and crevassed glacier, seen from the Aiguille du Midi
Crevassed ice and flow bands pour off the Mont Blanc snow dome, seen from the Aiguille du Midi. A wind cloud lifts behind the summit.
Trail over scree beside the Bossons Glacier below the Mont Blanc massif
A summer trail crosses scree beside the blue ice of the Bossons Glacier. Snow slopes and a sharp peak rise above the icefall.
Blue seracs and debris-covered glacier ice between rock flanks
Blue seracs and debris-covered ice between bare rock flanks – the Bossons Glacier falls toward the valley.
Heavily crevassed icefall of the Bossons Glacier below snow peaks
The heavily crevassed icefall of the Bossons Glacier climbs toward the snow peaks. Crevasses, seracs and flow lines fill the frame.
Glacier ice with seracs beside a dark rock wall at the end of summer

Ridge of the Chamonix aiguilles with the Aiguille du Midi, seen from Plan de l’Aiguille
From Plan de l’Aiguille: the Aiguille du Midi stands at the right of a granite ridge of Chamonix aiguilles, with scree and sparse alpine vegetation below.
Close view of fractured white and blue glacier ice with crevasses
Close to the ice: seracs, crevasses and flow lines form a dense white-and-blue surface.
Ribbed icefall with ogives below snow peaks and dark rocks
A ribbed icefall drops between snow peaks and dark rock outcrops, with ogives and seracs below.
Heavily crevassed, dirty glacier ice with seracs
Heavily crevassed ice: dirty seracs, flow ridges and scattered debris.
Blue-white glacier ice with crevasses and faint debris streaks
Flowing ice up close: crevasses, rounded seracs and faint debris streaks on a blue-white surface.
Snout of the Bossons Glacier above a grey debris fan and forest in the Chamonix valley
The fractured snout of the Bossons Glacier ends above a grey debris fan and meltwater channel, framed by the forested slopes of the Chamonix valley.
Blue glacier ice against a dark rock wall with pale scree
Blue ice presses against a dark rock wall and pale scree, seracs and flow lines packed tight.
Blue-white glacier ice along a dark rock flank with melt streaks
Ice against the dark rock flank: seracs, melt streaks and debris along the edge.
Broken seracs around a dark ice cave in the glacier
Seracs radiate toward a dark ice cave in the Bossons Glacier.
Field of angular ice blocks and shadowed crevasses
A field of blocky ice and shadowed crevasses – the raw surface of a melting glacier.
Steep icefall with seracs against a deep blue sky
Looking up the steep icefall: broken seracs stacked against a deep blue sky.
Angular blue-white glacier ice with thin crevasses
Angular seracs, thin crevasses and scattered debris – ice at the end of summer.
Blue-white ice blocks with deep clefts
Blue-white ice blocks, deep clefts and debris up close.
Chaotic icefall below snow peaks and granite towers in the Mont Blanc massif
A chaotic icefall climbs toward snow peaks and granite towers, broken seracs in front.
Broken glacier ice with debris streaks above Chamonix
Broken ice with debris streaks – the melt zone of the glacier above Chamonix.
Radiating crevasses and seracs on the glacier surface
Crevasses and seracs radiate across the surface in a dense pattern of dirty ice blocks.
Debris bands on the glacier below snow peaks
Debris bands cross the glacier beneath snow peaks and dark rock outcrops.
Crevassed glacier below the snow dome of Mont Blanc with a rock rib
Crevassed ice climbs toward the Mont Blanc snow dome beside a dark rock rib.
Glacier ice against a steep rock ridge below Mont Blanc
Broken ice leans against a steep rock ridge beneath Mont Blanc, snow peaks and a sharp summit beyond.
Ribbed flow bands and ogives on an icefall
Ogives and flow bands: the icefall becomes a pattern of ribs and blue shadow lines.
Icefall with ogives below Mont Blanc in sunlight

Diagonal ice ridges and blue-grey crevasses in the glacier
Diagonal ice ridges, compressed flow bands and blue-grey crevasses.
Icefall of the Bossons Glacier with ogives and seracs below dark rocks and snow peaks
The icefall spreads beneath dark rock outcrops and snow peaks, ogives and seracs in front.
