Yellowstone National Park took to Facebook yesterday to announce the New Blue Spring at Mammoth Hot Springs has ended its “recent period of dormancy.”

The New Blue is part of the Main Terrace Group on Clematis Creek at Mammoth Hot Springs in Yellowstone. Rather than being a single pool, the spring is made up of several different vents which means the pool shifts its position occasionally.
Relatively active throughout the recorded history of Yellowstone, the spring started getting quieter in 2005. The volumes of thermal water spilling over its edges began to lessen and the pool became more contained. In recent years, the pool usually appears empty.
