At least, that's what I remember from the film, and the Wikipedia page says "feet."
Also, I don't know if the Rockies have a 25,000-foot mountain (I think the Andes do, though).
Us Americans are kinda awkward about measurement units...
The highest peak in the Andes, is Mount Aconcagua, which is just under 7,000 meters. That’s the highest point in the Western Hemisphere.
