What length are the slopes and what are they made of?

The Ski Club has 3 different slopes. The main slope is 180 m long and the intermediate slope is 150 m long.  Both of these are covered with Dendix,a special bristle surface designed for ski slopes. They are lubricated with a gentle misting spray.    Our two new introductory slopes are covered with a soft springier Snowflex (the nearest thing to snow) and feature Travelator lifts and a low level misting system.
