ABSTRACT:
A snow making apparatus of the low profile snow gun type or of the tower type having independent and co-extending air and first water conduits supported above ground. Air and first water discharge nozzles are connected to the upper ends respectively of these conduits for producing a plume of atomized water from external interacting air and water discharge under pressure from the air and water discharge nozzles to produce snow in sub-freezing ambient conditions. A second water conduit co-extends with the air and first water conduits and a second water discharge nozzle is connected to the upper end of this second water conduit in the head of the snow gun or tower for discharge of additional water under pressure to ambient atmosphere through this second water discharge nozzle. An air valve is also provided in the head of the snow gun or snow tower and is connected to the second water conduit and the air conduit whereby the air valve disconnects the supply of air under pressure from the air conduit to the air discharge nozzle or nozzles when the air valve is subjected to water under pressure from this second water conduit.
