At this point, it's pretty much pass fail. All key lifts open is a pass, and key lifts closed is a fail.
Key lift is defined as a lift that is the primary or only one serving a terrain section. For example, the Gondola, Facelift, Summit, Lookout, and Bear Den lifts are what I consider to be the key lifts at Whiteface. I do not consider Mixing Bowl, Bear, Freeway, LWF, and Mountain Run to be key lifts. Mixing Bowl and Bear are redundant with the Facelift for the exact terrain they serve, and redundant with Bear Den for learning terrain. LWF, Mt Run, and Freeway are redundant with the gondola. Facelift serves the same terrain that the gondola does, but provides access to ability levels that the gondola doesn't and is a major access point, so it's a key lift.
