Rob,
I've been doing research on Stanley Thompson's Green Gables course at PEI. It seems 3-4 of the best holes in Canada were lost only 5-6 years after the course opened, in 1939.
Thompson routed these lost holes through the dunes, just down the coast from Crowbush. As you know, the north shore of Prince Edward Island gets pounded by storms, especially in the winter. The dunes ridge at Green Gables has shifted some 3 kilometres inland since Thompson's original course there opened for play.
I was at Crowbush the past spring, and looked at the massive and expensive operation that was underway to recreate and stabilize the dunes lost there last winter. Too bad they couldn't have done the same at Green Gables in the early 1940s. We'd probably be talking about Green Gables in the same breath as Highlands Links.
