Update: The 3D Map of Whistler has been updated to show the new Harmony and Crystal chairs, along with a access route called Crystal Glide. There are also a couple of other minor additions and corrections.
Today, Whistler Blackcomb officially announced that they are upgrading the Harmony Chair to a 6-Pack, and at the same time they announced that Crystal Chair will be replaced by a High-Speed Quad. Both chairs are expected to be operational for next season (2013/14).
Installing a 6-Pack in Harmony is long overdue, since the current chair (a high-speed quad) often has some extremely long lift-lines. This is because the Harmony chair accesses a huge area that is a favourite of many people. It is also the main way to access the Symphony zone.
The New Crystal Chair is in a slightly different location, with it’s load station being situated on the Blackcomb Glacier ski-out Road (near the bottom of Rock n Roll). It will continue to unload in the same place. This new high-speed quad will greatly decrease the time it takes to track out Crystal zone It will also shorten the time it takes to lap areas such as Spankys and the Blackcomb Glacier, which is a good thing
I expect they are going to do some MAJOR summer grooming in order to enable skiers to reach the bottom of the new Crystal chair. Currently there is a relatively long, slightly uphill section to be crossed to get from the bottom of the existing Crystal chair to the new location.
