Alaska Just Unlocked a Brand-New Island Thanks to Melting Ice
Alaska just got a surprise “real estate listing” from Mother Nature — a fresh, two-square-mile island popped up in Alsek Lake after the Alsek Glacier finally let go of its icy grip this summer.
For decades, a chunky little mountain called Prow Knob was stuck inside the glacier like a popsicle in a freezer burn. But as the ice melted back (climate change says hi), the glacier lost contact, leaving the mountain completely surrounded by turquoise water. Voilà — Alaska’s newest island, born between July and August 2025.
Glaciologists have been side-eyeing this breakup for years — one even predicted the glacier would dump Prow Knob by 2020. The ice held on a little longer, but now it’s retreating fast, with Alsek Lake ballooning from 11120 to 18500 acres since 1984.
And here’s the twist: while some folks panic about change, but it’s also a new opportunity. More open water means fresh habitat for fish, birds, and seals — and a brand-new island for adventurers to explore. Alaska isn’t just losing ice; it’s gaining wild, untouched landscapes that look straight out of a fantasy movie. Nature’s not ending — she’s remixing.
