Unfortunately, I noticed an error. The Committee’s Punch Bowl Bifurcation Island is much, much smaller than what is reported. The reason for this, I'm sure you'll be delighted to learn, is about half of that area is in fact another bifurcation island! See this unnamed lake in northern British Columbia here: 59°03'07.5"N 133°57'08.0"W This lake has two drainages. The east side drains into Sloko lake and then the Pacific via the Taku river. The west side drains to Atlin Lake, then Tagish Lake, from which flows the Yukon River, traversing all of Alaska to dump out into the far north Pacific just south of Nome. Thus the one large bifurcation island mentioned, is in fact two much smaller ones.
