Wasatch Powder Guides runs heli-ski (or snowboard) tours directly from Snowbird or Canyons resorts, which means you can hop in a helicopter as soon as the resorts get tracked out to be shuttled to another few thousand square miles of never-been-touched dry Utah pow. WPG tours average about 30,000 vertical feet per day, rarely repeating a line for 7 hours straight, and has permits to air-drop you at the best spots (they choose terrain based on your personal ability levels and whims) in the Wasatch and Uintas.
For the non-ballers out there, cat-skiing is usually less than half the price, but is just as convenient, feels almost as fancy, and still gives you all kinds of bragging rights to your friends back home. Park City Powder Cats operates out of Thousand Peaks Ranch, where they’ve cordoned off their own “private ski resort” that’s bigger than Whistler, Vail, Mammoth, and Snowbird combined. They cover their 40,000 acres of terrain in fancy, heated, 10-seat snowcats, where you can thaw out and grab some snacks between runs. A snack-wagon to powder-filled bowls, epic tree runs through the aspens, and steep lines of unbroken powder? Absolutely worth doing at least once in your life.
