While some snowmaking systems are nearly 100% automated, Big Bear Mountain Resorts rely heavily on skilled labor, although some of the newer fan guns are mostly automated. Crews of 10 to 20 men work day and night, when conditions permit, moving and setting the guns in place and adjusting the air/water mixtures. This is done by standing in the snow landing area in front of the gun examining the particles as they fall on their sleeve – or, pinching a bit of snow on the surface to test its consistency. If a little more or less water is needed, they signal to a man at the water hydrant to make the adjustment. They usually move around the mountain on snowmobiles and check and adjust each gun every hour or so. They are outfitted in waterproof suits with gloves, boots and ear protection (necessary because of the noise). They work long hours in some pretty adverse weather conditions, but it is very rewarding work as many of them ski or snowboard and take great pride in producing a product they use for their own pleasure when they have time off.
