This past weekend, Vanessa O'Brien became the first-ever American woman to successfully summit K2, one of the deadliest peaks in the world, as reported by Gear Junkie.

O’Brien, 52, made the summit with 12 other climbers on July 28, according to Gear Junkie, and because of her dual citizenship, O’Brien is also technically the first British woman to summit K2.

Forbes reports that this was O’Brien’s third attempt to climb the 28,251-foot mountain. Her 2015 and 2016 attempts were unsuccessful due to unfavorable weather conditions.

“This was by far the hardest undertaking I have ever come across,” she told VOA.

Gear Junkie reports that O’Brien also holds the Guinness World Record for the fastest woman to climb the Seven Summits, the tallest peaks on every continent.

O’Brien and her team started the summit from the Pakistan side of K2, and she raised flags for America, England and Pakistan once she reached the top.

K2 has only seen just over 300 successful summits on record, and is an extremely dangerous, technical climb.

“K2 fascinates me because while it is not quite as high as Everest, it is technically more challenging with exposed rock, steeper terrain and higher avalanche risk,”
O’Brien told Forbes
