In 2014, photographer Tim Taylor joined an expedition to the summit of Makalu, the world’s fifth tallest mountain. This is the story of their harrowing journey. 1/ wired.trib.al/pIRqEYQ

Makalu is an icy giant 14 miles west of Everest that straddles the border of northeastern Nepal and Tibet. Its four sharp ridges ascend almost vertically toward a 27,765-foot summit. 2/ wired.trib.al/pIRqEYQ

Taylor’s team featured eight climbers, five Sherpa, and a handful of cooks and other support staff. 3/ wired.trib.al/pIRqEYQ

Their route up the mountain's southeast edge involved 4.5 miles of slip-and-you're-dead ridgeline with no fixed ropes above 23,000 feet. 4/ wired.trib.al/pIRqEYQ

The team traversed for two and a half months. In order to acclimatize, they climbed and retreated for anywhere from five to 16 hours a day. 5/ wired.trib.al/pIRqEYQ

One day, an electrical storm without any thunder or lightning hit. The air and their metal equipment hummed.

"We began to receive painful electric shocks, like hundreds of tiny needles being driven into your skin," Taylor says. 6/ wired.trib.al/pIRqEYQ

Then everything fell apart. A blizzard rolled in, forcing them to retreat back to base camp as it demolished tents and buried rope lines.

It ultimately claimed dozens of lives in the region. 7/ wired.trib.al/pIRqEYQ

They made one last push and reached a height of 26,250 feet, but by then they had been living at an extreme altitude for so long that each had lost more than a dozen pounds. With temperatures plummeting, they abandoned their quest for the summit. 8/ wired.trib.al/pIRqEYQ
