Burton Open - New Zealand
Snow Park NZ’s superpipe is the Southern Hemisphere’s only Olympic and X Games standard halfpipe. It has taken 10 days to shape for the event, uses 70,000 cubic meters of snow and 2.5 weeks of snowmaking. The pipe is 5.5m deep, 160m long and 18.2m wide with a 17 degree pitch. The quarterpipe is equally monstrous at a massive 10.3m tall and 24.3m wide.

Perisher Blue PSP Superpipe - Australia
Nine thousand cubic metres of snow was used to create the superpipe with over ten days of intensive labour. The result is a thirty metre longer, one metre wider and five metre higher pipe than last year. In layman's terms that means 125metres long, 17metres wide, 5metres high and a steeper angle.
