Cavers Discover Entrance Using an Infrared Camera
Found in early March 2013 in Greenbrier County, West Virginia, the small cave was named after the Tamarisk 320 infrared imaging camera that was used to find it.
The discovery was captured by Neha Gupta, a graduate student at Ohio University, who made and stars in the following video featuring the initial find and subsequent excavation of the entrance to Tamarisk 320 Cave.
Although the passage soon became too low, it continues with good airflow and the floor remains diggable.
