The Underground Natural Wonder In Alaska That’s Positively Unique

Permafrost is a thick subsurface layer of soil that remains permanently frozen throughout the entire year. In the arctic coastal plains of Alaska, this incredible natural wonder can extend roughly 2,000 feet below the earth’s surface. In the last frontier alone, you might be surprised to learn that permafrost is found beneath nearly 85% of Alaska’s land.

Permafrost is thickest in the arctic regions of the state of Alaska, north of the Brooks Range. With most of the permafrost in Alaska being tens of thousands of years old, there is no doubt that you’ll be positively mesmerized by how this natural wonder effects Alaska’s terrain.
