Intrepid former U.S. MarineKirstie Ennishas begun the climb of her life!
The veteran — who survived a helicopter crash in Afghanistan in 2012 that resulted in severe injuries and required more than 40 surgeries — has arrived at Base Camp on herEverest expeditionthat sees her hoping to be first female above-the-knee amputee to scale the world’s most famous — and highest — mountain.
On Monday, she posted a new photo at Base Camp that showed her practicing ice fall climbs. “Just making sure we’ve got our systems dialed,” she captioned thephoto on Instagram. “The boys will be doing a little recce on the ice fall this morning so we can double check everything else!”
After a period of acclimatization hikes in the lower reaches of the mountain in Nepal, she and her team have been slowly progressing these first stages in order to avoid altitude sickness.

“It has sunk in that I am actually going to climb Everest,” Ennis tells PEOPLE. “For the last year and a half, I have talked about making this happen. And now here I am. I try my hardest to do as I say, and say what I mean. This is now the truest testament to that.”
Ennis says she has been experiencing a “twisted kind of excitement,” as she has been daydreaming about dragging her body through an ice fall, “teetering on ladders across traverses.”
“I could nearly feel the pain I was going to put my body through,” she adds. “To motivate myself, I do visualize summiting Everest. But what if that actually happens? We may actually be able to pull this off. I may actually stand on top of the world on one leg.”
This expedition feels very different from the other mountains she has scaled “because of how hard I have worked for this,” she adds. “It’s also different because of how it’s affected those around me. Because Everest is so well known, and famously dangerous, my friends and family have been very vocal about how they feel. It worries everyone which puts a bizarre sense of guilt over me.”
“This really is a test of everything that I have trained for at this point.”
