Sounds to me like a major rehab in the future.
I was lucky on my last trip that the Yeti was still working. From what I could find it has been turned off since late March or early April.
We had a few threads on the construction of this attraction somewhere in our base.
I know that the attraction was built on three different set of footings.
One for the mountain, one for the ride and a heavy one for the Yeti. This was supposed to prevent the problem that is now happening with stress cracks. Oh well , looks like they did not get it right.
Such a shame.
