Blue - Intermediate difficulty slopes with grades commonly ranging from 25% to 40%. These slopes are usually groomed. Blue Square runs make up the bulk of pistes at most ski areas, and are usually among the most heavily trafficked.

Balck - Amongst the most difficult at a given mountain. Black Diamond trails tend to be steep (typically 40% and up)[1]

The above numbers a not accurate, not a surprise as Wikipedia is not known for the truth, whole truth etc.

In the east, only the very steepest trails approach 40 degrees (not slope). The front 4 at Stowe are high 30's. Trust me, those 4 are very expert.

In the Rockies, Palavencini at A-base is known to be just over 40 degrees over it's length.

For very short pitches, may trails have plus 40 degrees.
