Why does Marina not want to go back on the lift?

Marina wants to ski back rather then take the lift. Unlike Tom, Marina isn't worried.

"Oh, Tom," laughed Marina. "You’re not in Barrow, up above the Arctic Circle, anymore. You're not on pipeline patrol on the permafrost. You're here in lower Alaska. You can relax."
"It’s a glacier-covered mountain, the sun will soon go down, and a wind is coming up. At home, we don't take nature for granted. We're Inuits, and we're supposed to understand terrible weather."
Marina bristled. "I know this-mountain. I work here on weekends. All that we have to do is follow those ski lift pylons back to the base lodge. Those posts will be our markers. Come on, I'll race you!"
