We were carrying everything we needed. There would be no villages or resupplies on our route. We carried food for 25 days. We had camping equipment, and ropes and crampons for the glacier crossing. There was a fair weight of camera equipment, batteries and solar panel chargers. And we also were carrying all the gear you need for paddling glacial whitewater rivers. The weight of the packs crushed our knees and spine and gouged our shoulders and hips. We feared that we had bitten off more than we could chew.
