Skier,
Your list is missing at least these (see early post this thread pg 1):

TELLURIDE
Lift 8 (Oak St) 42.7% (v-1055; h-2470; sl-2686)
Lift 7 (Coonskin) 42.4% (1845; 4350; 4725)
Lift 14 (Gold Hill) 44.3% (1475; 3333; 3645)
Lift 6 (Apex) 42.0% (1144; 2727; 2957)

And I am skeptical about your reference re:
Snowbasin, Utah Mt. Allen Tram Aerial Tram Doppelmayr 1998- 1047 1165 0.898712446

89.9% is very steep for an aerial lift. I haven't found horizonatal or slope length or ride time specifications to confirm or refute your claim, but just to suppose you are correct, given a vertical rise of 510 feet, then the slope length would be something like 762' making the ride time at 5 m/s approximately 45 seconds and at 10 m/s 23 seconds plus a little for acceleration and deceleration at the terminals. Does this sound correct to you?

The www.skistats.com website gives the Olympic Tram (aka Mt Allen Tram) at Snowbasin a vertical of 510 and a slope length of 1165, so that calcs out at 48.71% (a little over 1 minute ridetime at 5 m/s rope speed). But this site also suggests that the Viking 3C at Deer Valley has 135 vertical over a slope length of 150 for a whopping 206% gradient, so... who knows?

Seventh Heaven at Stevens is steeper by far than Tye Mill, yet it's not on the list? I calculate it at only 39%, yet it doesn't seem flatter than either Tye Mill or Southern Cross. You also have to keep in mind that Southern Cross/Double Diamond is an up-and-over lift; you're calculating the average gradient of both sides because SAM adds the vertical of both sides and runs the total length of the installation.

7th Heaven is a very steep, short lift. An interesting note about it is that the large rope deflection angles at the top and bottom increased the line friction above that which was expected. After the load test, it was unloaded by backing the load down and it stopped overhauling much sooner than expected.

The data sheet I have for 7th Heaven is 441' rise and 772' horz, but for some reason it says 1000' slope length, and the qty of chairs matches 1000'.

Unfortunately, I don't have access to the profile anymore.

Your numbers (which I assume are much more accurate than mine) make it 57%. I would guess rope weight on those sheaves is pretty heavy- I'd hate to have the rope jack fail while changing a sheave!

CCslider, I am going by the skilifts.org surveys, which put the Olympic Tram at 89% which is probably wrong, but not by me.

Where are you getting your numbers for Oak Street? I can't find that lift in any of the surveys.

For Coonskin, my numbers from SAM put it at 38%.

Gold Hill with the numbers from Doppelmayr is 40%, not in the top 20

Apex could be that steep, it was a relocation so I did not have numbers for it. If you know your numbers are correct, then I can add it, but the numbers from SAM do not agree with most of yours.

Oak Street is the former Palmyra lift I believe. That's why it's not listed on the lift installation surveys.

I will check the stats for the Olympic lift this weekend.

The Doppelmayr Worldbook puts it at 155m x 355m, or 509 ft x 1165 ft, or 43.7%

Oak St (Lift 8) was relocated in 1985 - it used to be the orginal Gorrono Lift 4.

Let's just say I'm fairly familiar with the Telluride Lifts:

Oak Street (L8): 1055 v, 2470 h, 2686 sl = 42.7% (1972/85 SLI/CTEC)
Coonskin (L7): 1845 v, 4350 h, 4725 sl = 42.4% (1975 SLI/Riblet)
Apex (L6): 1144 v, 2727 h, 2957 sl = 42.0% (1985/99 CTEC/Doppelmayr)
Gold Hill (L14): 1475 v, 3333 h, 3645 sl = 44.3% (2001 Doppelmayr)

The vertical and slope length numbers come from as-built profiles. The horizontal and % gradients are mathmatical calculations (my math is always subject for debate).

I can't be sure, but I'll bet that the "Bridal Veil Falls" tram in Provo UT was the steepest ever. I rode that thing atop the gondola from top to bottom - it was a crane.

I'm pretty sure the triple chair at marmot is not deserving to be at the top of the list, i'm not sure the exact stats but i wouldn't put it as the steepest lift around. And as far as i know there have only been Doppelmayr lifts there.

Are these stats for lifts that are still standing? I guess that would make sense. Any idea what the old Beaver lake lift would have been?

I think Beaver Lake is the lift in the survey with a vertical of 300' and length of 1005' so that would put it at 30%

English majors they were not... but the thing indeed was steep.

I recall looking up the line at Bridal Veil Falls and saying that I didn't think I'd want to do a carriage ride.......!!!

Big Sky Tram? Here's a pic looking up the line.
