This website has lifts listed in order of steepness:
Unfortunately it's not always accurate. According to the URL above Thunder chair at Jackson is 2612/1456 = 1.79. That smells wrong in view of Sublette being 4108/1630 = 2.52
This site http://www.skilifts.org/old/ has been around for awhile and is often the go-to source for lift stats. It agrees with the other site on Sublette but has Thunder at 3612/1456 = 2.48 Looks like a typo on http://www.skistats.com/slopes_.asp?state=WY
Here's Colorado for http://www.skistats.com/slopes_.asp?state=CO
#3 is Deep Temerity 4300/1800 = 2.38 http://www.skilifts.org/old/co-highlands.htm says 3683/1708 = 2.16, exact stats quoted by Bob Barnes
#2 is Timberline at Winter Park 3825/1712 = 2.23 This is obviously wrong. skilifts.org does not have stats for this lift but Google Earth says it's 7181 feet long.
#1 is Silverton's lift 3700/1712 = 2.18 on http://www.skistats.com/slopes_.asp?state=CO
That could be right, but given widespread errors on that site (check http://www.skistats.com/slopes_.asp?state=WA for more conspicuous errors) I'd want a corroborating source.
We have an issue with quality of data sources. http://www.skistats.com has the data organized the way we want for this search but has numerous errors on their lists plus a likely small inaccuracy for Temerity. http://www.skilifts.org has more limited data but better accuracy. However, it's wrong for the Lone Peak tram at Big Sky, claiming only 833 vertical, which is probably a miscopy from the Lone Peak triple chair.
Both sources agree that Scott at Alpine Meadows is 2250/1068 = 2.10
If the ratio is close, I think length matters a lot in terms of the ski experience. Temerity is a tougher challenge than Scott IMHO.
