It is kind of hard to tell, especially since it is built on a hill, but I was guess closer to 130. Most of that is based on the assumption that a level of supports is 6.5 feet. I remember someone posting that once, and the math seemed to work out for the turnaround being 90 feet tall which people seemed to agree on. However, I guess there is no real proof that the turnaround is 90 or that the support levels are 6.5. Also, not all the support levels seem to be even on the lift, but most are. If the turnaround is 90, then I think the lift has to be well over 100.
