Analysing terrain data
The Beaver Slides are kind up an upper extension of Keystone Ridge.
When the Silver Queen Road wraps under the Patrol Shack after Triangle, there is a short open pitch on your left above a cat track and some trees.
Those trees are the Beaver Slides.
There is a more open section with moguls on the right above the opening for Elevator Shaft in Keystone Ridge.
The skier's left side of the trees over the middle of Keystone Ridge can be a little steeper with more variable snow over the embankment on to Ruby Road which can sometimes be a 5-10 foot move.
You can ski Triangle under the Twister Lift and hang right to catch the skier's left section of Beaver Slides.
