It's a good tired, as they say.
We only skied for like four hours, but we're all pretty exhausted. I haven't been living at altitude this summer — Denver is only a mile high, but Portillo is the same as Winter Park, 9,000 and change at the base, and going well upward from there. So there's that, and the fact that we haven't been on snow since July. In fact, many in our group haven't skied since April.
The mountains here are pretty epic, and they surround a small alpine lake, the Laguna de los Andes. Some of the off-piste skiing requires you to traverse across the frozen lake once you get to the bottom.
I posted photos from our crazy night in Santiago on my Facebook page... check em out.
