Corkscrew isn't particularly steep, but it it narrow, and it sees a lot of traffic, as it is the only green run alternative to Sugar and Spice on the Grandview side.
Better suited to beginner snowboarders as it's not as flat as Sugar and Spice.
It's a series of relatively narrow switchbacks that winds it's way down to the top of Rock Garden chair.
When navigating Corkscrew, take it slow, and watch out for the berms that form through traffic cutting in tight at the corners.
Best done in the morning when it's not to busy.
This run is in the shade, so will tend to keep whatever the seasonal conditions are.
