which of the following is not a difficulty rating for a ski slope?

The option that is not a difficulty rating for a ski slope is the Pink Triangle.

Standard ski slope ratings

In North America, common ski slope difficulty symbols are:

• Green circle (beginner)

• Blue square (intermediate)

• Black diamond (advanced)

• Double black diamond (expert only)

In Europe, ski slopes are typically colored:

• Green or blue for easier runs

• Red for advanced

• Black for expert

None of the widely used systems include a pink triangle as an official difficulty rating, so that is the one that does not belong.
