I'm pretty sure most ski resorts have your basic Green circle for beginner, Blue square for intermediate, Black Diamond for hard, Double black diamond for extremely hard. I've only been skiing for 2 years, I picked up pretty fast Cause I play hockey, I can do the blue square pretty good now. But I'm unsure about black diamonds, so does anybody know how much of a jump there is between a black diamond and a blue square? And it will be an even bigger help if you've ever been to Kissing Bridge, the link is there website.
