Crashed Ice is a combination of Speed Skating and Snow-cross, which in it’s self is a combination of Downhill Skiing and Motocross.
Basically, it’s been 400 years since a fully original sport was created. Crashed Ice is an extreme example of the constant appropriation in sports. No one owns a sport, so everyone can do whatever they want with it*
*If the sport requires a giant frozen obstacle course it might be the case that any company with the rights to the major leagues essentially owns the sport. (Looking at you Redbull)
