Gore marketing has implied that the new run under the skibowl liftline is the second only to Rumor in steepness. So…Rumor, Skibowl Liftline, and then Lies comes third? I’ll tell you one thing…SkiBowl Liftline LOOKS pretty steep on the topo. But that pitch was originally a “T” Bar. How could it be that steep?
I decided to see if I could figure it out. I have a hard time with grade to degree conversion. I have no idea if these numbers are correct and I’d like to be corrected if I’m off. On the Gore website…in the History Timeline…they list the dimensions of the original ski bowl T-bar as 3000′ long and 830′ of vertical. The new lift uses this same run…so I’ll assume those numbers are close. On that same page, the percent grade for Rumor is listed at 70%. It’s undetermined if that pitch is for the headwall or the average of the whole run.
I asked a mathematician to figure the horizontal run for the triangle that has 830′ vertical along the y-axis, (TBD) horizontal on the x-axis and the 3000′ ski lift as the “hypotenuse” of the triangle. The number for the “run” (as in rise/run) is 2,883. So I figure the grade% for the new lift as 830/2883 = or 29%.
Here a some grade and angle conversion numbers I got from Tony Crocker of bestsnow.net:
- 100% grade = 45 degree angle
- 75% grade = 36.9 degree angle
- 50% grade = 26.6 degree angle
- 25% grade = 14 degree angle
According to the website’s 70% number this would put Rumor around 35 degrees which jives with numbers I’ve heard in the past for Rumor.
Extrapolating the SkiBowl’s 29% might average around 17 degrees. There’s nothing to say that PARTS of the Ski Bowl slope couldn’t approach parts of Rumor for steepness, but on average it looks less steep. Hard to believe most of Lies isn’t steeper.
