i think technology is really having a positive effect. snowmaking is becoming a bigger part of it. we can make snow through our fan guns in —2 temperatures so that guarantees local ski schools and that business, it's a busy time coming up. then combined with natural snow and temperatures we can get snow guns going and we can snow farm and start building a base and really the base is key to trying to maintain the snow throughout the season. thank you so much, jim, for explaining how snow production and all your adaptations are so vital to the industry here. i'm going to head now and find out a little bit more aboutjust how you make snow at the top of a mountain. i'm here at the snow factory now, where the man—made snow is produced. mikey, you're head of engineering here at cairngorm mountain, so you're very much in charge of running this machine and producing the snow. talk me through, how does it work? it's an ammonia plant, pretty similar to some fridges and freezers. this cools an ice—maker.
