Ski Resort Guide Library

I'm looking to build out my library of ski books.

Specifically, I've been trying to find the "Official Unofficial Guide" to some of the bigger resorts or popular backcountry areas. Below are some of the ones I've found so far. I'm sure everyone has a book they've followed, but I've found that these are generally considered "the bible" for their respective areas:

Squaw Valley: Squallywood - Robb Gaffney
Bridger Bowl: Stepping Up - Tavis Campbell & Sam Cox
Wasatch Backcountry: The Chuting Gallery - Andrew McLean

As you can see, this list is fairly short. I'd love to hear what some people use as references for their home resort, favorite travel destination, or anything in between.

If a thread like this has already been made, feel free to point it out for me.
