Really? I thought I had read 50' somewhere?
While I don't know the actual height, it's not that hard to guess about what it will look like.
The few easy rules:
Higher towers that are far apart allow for a larger sag in the line and still have the low point high enough.
More towers allow for less of a sag and a more constant height.
We have no idea the number of towers, but the easy guess is somewhere in the middle range balancing how many, height, and distance between them. Higher is more expensive, greater number of shorter is more expensive. Someplace in the middle is a balance.
But, the even easier height guess is based on the road crossings and rescue equipment. In the woods surrounded by trees the height doesn't matter much. For rescue, they already have monorail rescue equipment. Something about the same height, or within the capabilities of that existing equipment would minimize the need for new stuff.
Finally, the road crossing are the real determination. Minimum height of the bottom of any car needs to be taller than the normal truck traffic road height plus some safety margin. The easy guess for this is the bottom of a car will be at least as high as the top road surface is above the lower road service where there are overpasses. Trucks already have to be able to pass under the overpasses, and the overpass thickness is a stand in for that safety margin.
The other road consideration is oversized load restrictions. Things like when they bring in a huge crane or water tower or other gigantic item. If all the roads being crossed already go under overpasses, the overpass already sets the limit for that stuff. If one of them doesn't though, then the cable (not the car bottom, so a different measure point) should be high enough to allow any future oversized load to pass under the cable. They can remove the cars, but getting the cable out of the way is a lot more work. Not impossible, but if they already KNOW they've got cranes that need to pass through and the cranes are X feet tall and already following special routes to avoid overpasses, they'll not want the cable to complicate that already messy process.
Thinking about all of those, you can kind of visualize something balanced in the middle. And it's nowhere near as tall as the Whistler PEAK 2 PEAK is. Probably lower than many ski lifts too.
