Tried looking it up, it’s so new that nobody who knows has made a post about it yet. Slow day at work so I’ll try and crack the case via wikipedia or whatever

Edit: alright so the spot really is freaky

Although the mountains are formed from ancient rocks more than 1 billion years old, geologically, the mountains are relatively young and were created during recent periods of glaciation. Because of this, the Adirondacks have been referred to as "new mountains from old rocks". It is theorized that there is a hotspot beneath the region, which causes continued uplift at the rate of 0.6 to 1.2 inches (1.5 to 3 cm) annually.

The Adirondack mountain range has such unusual characteristics compared to the area around it that it is divided into its own province within the Appalachian Highlands

Basically the mountains from that entire region formed around the same time from the same glacial event but these ones just randomly popped up much later and we really aren’t precisely sure why
