Two unassuming buildings, painted in the resort’s signature white and green, rest at the base of the mountain.  One is the pump house, the other, the compressor building.  More than thirty-five miles of underground pipe issue from these buildings, servicing 250 HKD tower guns and 45 ground guns.  The compressor building maintains a pressure of 100 psi in the pipes. The hydrants connected to the pump house are adjustable between 200 and 600 psi.

Holiday Valley’s system, a descendant of the Bob Crone prototype, is entirely air-water, two lines run into each gun, and through a mixing nozzle.  The modern HKD towers give the artificial snow more time to crystallize in the air before it lands, but the ground guns have the advantage of being moveable, reaching places where HKD towers can’t be installed.
