Within a 20-kilometer radius of the Baltoro Glacier's upper reaches, four peaks exceed 8,000 meters: K2 at 8,611 meters, Gasherbrum I at 8,080, Broad Peak at 8,047, and Gasherbrum II at 8,035. The glacier itself stretches through the heart of the Karakoram range in Pakistan's Gilgit-Baltistan region, collecting ice from a constellation of tributary glaciers that drain these giants. Where the Baltoro meets the Godwin-Austen Glacier descending from K2, a junction called Concordia opens into a natural amphitheater of rock and ice that mountaineers have compared to a cathedral nave -- except that the ceiling is the summit of the second-highest mountain on the planet.

Baltoro Glacier: The Architecture of Ice

Its surface is a chaos of moraines, crevasses, and glacial debris -- not the clean white expanse that the word "glacier" might sugge...

K2, the savage mountain, rises at the glacier's head -- a peak with a fatality rate that far exceeds Everest's. Broad Peak and the four Gasherbrum summits line the easter...

Baltoro Glacier: Concordia and the Trek

Wed, 25 Mar 2026 00:00:00 GMT

Photo credit Vittorio Sella, Public domain. Every expedition to K2 and most climbs of the Gasherbrum peaks begin with a trek up the Baltoro from Skardu, the Balti town that serves as the principal gateway to the Karakoram. The journey takes roughly a week on foot, passing through campsites with names that have entered moun...

Baltoro Glacier: Garbage on the Glacier

Wed, 25 Mar 2026 00:00:00 GMT

Photo credit Black Zero, CC BY 2.0. Improved road access to Skardu has transformed the Baltoro from a destination for elite mountaineers into an increasingly popular trekking route, and the consequences are visible at every campsite. Litter, inadequate sanitation, and the heavy use of overburdened mules have left t...

Baltoro Glacier: Seen from Above

The scale becomes comprehensible only from this altitude -- the glacier's length, the enormity of the peaks that flank it,...
