Actress/singer Mandy Moore celebrated America’s Memorial Day holiday at Mount Everest’s base camp in Nepal after successfully completing the grueling trek. You go, girl!

The This Is Us star achieved her goal on Sunday after spending more than a week hiking through challenging terrain with a trio of friends, including experienced Alpine guide Melissa Arnot.

She documented their victorious moment with an Instagram photo, in which Mandy and her pals jump for joy with their arms outstretched in triumph at the top of the world.

Moore explained the feat was far from easy, detailing the challenges she faced hiking through Nepal’s terrain in pursuit of the base of the world’s tallest mountain.

“Breathing at altitude, for instance, is not easy,” she wrote.

“Besides hydration and staying nourished, breathing is THE vital key in the fight against altitude sickness. It’s also a major takeaway that I will be employing back to the real world whether I’m in the midst of a tough workout or a weird day. Mind blown.”

Moore reflected on the mountaineers who came before her and paid tribute to the hikers who have died on the immense peaks.

“It’s impossible to be lucky enough to arrive at the foot of these mammoth peaks and not be attuned to the palpable energy of all of those who came before and lost their lives in these mountains,” she wrote.

The actress continued: “The wave of emotion: respect, reverence, appreciation….that washed over us as we took in the prayer flags and yellow domed tents of basecamp AND sat on the rocks regarding the chortens that dot the hillside of the Tukla Pass the day before, profoundly.”

So far, 11 Everest hikers have died trying to reach the summit this season.

According to The Washington Post, one of the contributing factors is overcrowding. When too many people try to ascend at once, it creates a backlog, leaving climbers at deadly altitudes for an extended amount of time.
