Frontside is a revamped Silver Fir. It will not look the same as it was as the towers have been completely rebuilt. The backside utilized the Keechelus and Little Gold riblet double chairs and have also been rebuilt. There is a diesel generator up top which I believe will be the power for the Hidden Valley chair as well as utility power for the lifty building at the triple (just a guess looking at the conduit runs they have made). The Hidden Valley chair will be a top-drive.
