Skiing is the use of wearing ski's and gliding over the snow. The are many different types of skiing. The sport evolved from shoeing and now ranges dozens of variations of the sport. Skiing is now done primarily for recreational use across the world and is very popular in North America and Europe. Skiing originally came from snowshoeing and was a means of transportation from one place to another in the snow. The earliest form of skiing was cross country skiing. At many downhill slopes in North America ski runs can be classified into the following types of runs.

Types of slopes at a ski hill

Green: A green hill is known as learning or beginner slope. These trails tend to be large open, and gently sloping areas on the ski hill.

Blue: A blue hill is an easy trail, similar to the North American Green Circle, and are almost always groomed, or on so shallow a slope as not to need it.

Red: A red hill is an intermediate slope. Steeper, or narrower than a blue slope, these are usually groomed, unless the narrowness of the trail prohibits it.

Black: An expert slope. Steep, may or may not be groomed

Double Black: This type of run is the most difficult type of slope to ski. Harder then a black diamond slope, this type of slope maybe groomed or not groomed.
