Snake on a (vertical) plane, part 1

Fermilab staff spotted this 18-inch-long fox snake in the NuMI pre-target area, which is about 130 feet underground. The snake was on the cavern wall 4 feet above the floor. With glove-protected hands, AD’s Tony Busch removed the snake and gently placed it in a bag. The staff returned it to the tall grass of the surface. See part 2. Photo: Tony Busch, AD
