Jessica Biel, Emile Hirsch and Isabel Lucas trudged through a blizzard Monday on the fifth day of their hike with other entertainers and activists up 19,340-foot Mt. Kilimanjaro.
“It’s pretty gnarly,” Elizabeth Gore, an executive with the United Nations Foundation, and one of the participants of the trek to raise awareness of global water issues, tells PEOPLE by satellite phone. “The visibility is only 10 feet in front of you. And it’s cold. I’ve got six layers on.”
With just a day left of climbing before hitting the summit of the Tanzanian mountain, the group reached 16,000 feet, causing many to experience headaches and stomach problems due to the high altitude.
