Here's a green course on the 1992 version of Green Lakes (1:15000, 5m contours). Note: file size is about 1.3 MB (for anyone with a slower connection).
According to CNYO's map page, the Happy Valley map was originally made at 1:30000, leading me to believe it was used for a Rogaine, and that Mark is producing a new map for the A-meet. I don't have a copy of the Rogaine map handy (if at all).
