Then you have the European ratings that are Green, Blue, Red and Black.
For those old enough to remember, prior to a uniform system across North America, they were some interesting case across the East. Sutton used to have the European system until maybe the early 1980s.
Here are some of my Eastern favorites from the 1970s:
Smugglers Notch VT (1978-79): http://madpatski.wordpress.com/2011/12/26/monday-mad-addicts-attic-smugglers-notch-vermont/
Green Triangle (easy)
Blue Square (intermediate)
Red Circle (expert)
Mont Tremblant Lodge (1973-1978 map) : http://madpatski.wordpress.com/2011/04/18/monday-mad-addict’s-attic-mont-tremblant-lodge/
Green Square (easy)
Yellow Triangle (intermediate)
Blue Circle (expert)
So Smuggs and Tremblant agreed on a few things; circle were expert runs (red or blue) and green (triangle or square) were easy.
