This Fascinating Tunnel In Alaska Has Literally Frozen Time
The U.S. Army Corps of Engineers Permafrost Tunnel is a fascinating place. Located in Fox, Alaska, the tunnel was constructed in the 1960’s to study permafrost, or permanently frozen ground. Due to the long months of freezing temperatures in Interior Alaska, in some places the ground stays frozen… forever. This leads to a unique environment where the past is literally frozen in time. Virtually explore the Permafrost Tunnel to learn about the Alaska of long ago. In the virtual tour, you can see remains of animals and plant life from different eras dating as far back as 33,000 years! Taking the virtual tour of this tunnel is like walking into the Earth to see the past frozen in time.
