The article mentions that in all likelihood no human being has ever set foot on it, which seems plausible given that there's never been a large human population in the extremely large surface area of Victoria Island, and it's hard to imagine what would be so enticing about this particular splotch of land that it would possess a pre-contact Inuit to schlep a boat across all the portages necessary to get to it.
My point being, at least as far as dry land is concerned, this may be the best "discovery" opportunity left out there. I mean, obviously that's the wrong word, but you know what I mean. The best chance at a geographic "F1RST P0ST!!!1!1!" to use the vernacular of our times. Obviously if it's true that this place is totally untouched by humans, it's true of tons of random sandbars in the Arctic, but this one is special, if only in the mildest possible sense.
Seriously, we've been to all the other "-est" places on the surface of the land. Highest, driest, wettest, lowest, most isolated, northernmost, southernmost, you name it. We've stood on every pole you can imagine. I have a friend whose life mission is to stand on all the U.S. "triple points" (where three states meet) and honestly that's kind of what's left to us in terms of that kind of accomplishment. Yeah, there's "newest," whenever there's an undersea volcano, but that's fleeting. You're only the first guy on new land temporarily, because there will always be another new island popping up.
So if there's a more impressive distinction (and I admit it wouldn't take much) that we haven't landed on, I'd love to know about it. Otherwise I'm off to talk to the King of Spain about funding my forthcoming voyage of discovery to the inland wastes of exotic Kanata.
