The Centrefold girls (1974) ?

Can anyone please help me put a name to a film that I have been trying to get hold of for years? The film is a 70/80's film about a group of Models who go on a ski lift up to the top of a mountain for a photo shoot and are killed off one by one. I think their is snow up there, and one of the Models walks around with a baby Leopard in her arms. I originally thought it may have been the calender girl murders but it wasn't, now I am thinking that it maybe the film I have titled above, but can find few details on this film on the web. any help would be appreciated. Thanx!
