Ah Ha! I have climbed at Lake Luise. The lake and hotel remind one of none other than Skytop's hotel and Lake Mohonk. Those quartzite edges aren't quite buckets but close enough. But the main reason I did not include it- the cliffs are rather small so there aren't that many routes, but no shortage of spectators! Also, Skaha which I mentioned, is so much better and with hundreds more routes (and better weather).
Lake Luise gets honorable mention. But Skaha IS the Canadian Gunks.
