Gary Larson, facility operations manager with the Cold Regions Research and Engineering Laboratory, points out grass older than 10,000 years that has maintained enough chlorophyll to keep its green coloring within the permafrost during a tour of the U.S. Army Corps of Engineers Permafrost Tunnel on Sept. 12. The only one of its kind, the Army and CRREL maintain the permafrost tunnel to allow research on permafrost and how it affects climate change.
