Student nurse Hannah Phillimore, from Ryhall, helped raise more than £2,000 for the Edith Cavell Nurses Trust by climbing Mount Edith Cavell in Canada.
The mountain is three times the height of Snowden and took 17 hours to climb.
Describing her experience, Hannah said: “I traveled this August to Canada to meet 70 people, half of whom are nurses, who I did not know for this week of challenges. The week’s challenges included white water rafting, glacier walking and rock climbing, but the biggest challenge of all was to climb to the summit of Mount Edith Cavell.
“The mountain is 3,363m high, which is three times the height of Snowdon, and is one of the highest peaks in the Canadian Rockies.
“On summit day my alarm went off at 2am and we left at 3am. The first part of the climb was all through pine forest. It was about 15km, we had head torches on in the pitch black, and we had three hours of trekking before you could even see the mountain.
“After this stretch we had to climb a scree slope which must have been at least 300m. Lose rocks were under your feet and it was very scary knowing how high you are and how easily you could fall. It took another three hours to reach the top of this section.
“Once at summit ridge, two hours from the summit, it was very cold, covered in snow and you could literally see over each side of the mountain. At this point half our group turned back and myself and three others carried on to the summit.
“We had to traverse around the edge of the mountain in the snow with nothing to hold onto to, a sheer drop to our right and we were only roped to each other. It was terrifying.
“When we finally reached the summit at about 11.50am I was very relieved. It had taken us around eight hours. To get down was just as tricky, it took us about nine hours and we didn’t get back to the hotel until 10pm. It was mentally and physically exhausting but very rewarding.”
