Replying to Resorts' Adaptation to Freestyle Skiing

That's the title of a research paper that I'm writing for my 11th grade English class. My thesis is 'Terrain parks, special equipment, and freestyle competitions have aided ski resorts in the adaptation to freestyle skiing.' So as i start to do the research for my paper, I notice that every site I come across is like somebody's personal page with shitty information. So if anybody knows where i can get information on shit like what features have been added to ski resorts, such as different rials, jumps, etc. I'd appreciate it. The only thing is that they need to be reliable sources, not personal pages that say 'terrain parks have jumps like table tops, hips, and spines', it would help if the pages included a timeline. Any information at all would help. Thanks.
