Guster is one of the flattest blues on the planet. The first part of it you have to pole down until you get under the duck and it empties out to Eggbeater. Guster is nothing more than a connector trail to get to Eggbeater and Jet Stream. It starts off the top of the Spruce Triple and goes down to the top of Eggbeater. I would not recommend this trail because you can't get any speed up on it. Although, if you want to ski Eggbeater, and the duck isn't open, then this is the only way to go.
