Southern California's Secret Snowmakers

In Southern California, where warm winters are common, ski resorts rely on advanced technology and dedicated teams to create snow. This isn't just about flipping a switch; it's a complex process that requires specific weather conditions and a lot of effort. The resorts use two main types of snow guns: air and water guns, and fan guns. Air and water guns are fixed in position and work well in marginal temperatures, while fan guns can be moved around and are more energy-efficient. The best conditions for making snow are when nighttime temperatures drop to the low 20s, with low humidity and light wind. Making snow is a round-the-clock job. Crews work through the night to take advantage of the right temperatures, often only having a few hours to work with. Once the snow is made, it's moved around the slopes using snowcats and shovels to create smooth pathways for riders. The process doesn't involve any chemicals, just compressed air and water pressure. Heavier snow is used for the base, and a lighter layer is used on top to make it fluffy and soft. The resorts invest millions in snowmaking equipment and technology to ensure they can create snow efficiently and sustainably. However, there are challenges. Power outages, high traveler numbers, and strong winds can all impact snowmaking operations. Despite these challenges, the resorts are committed to providing a good base for customers throughout the season. While some people might think that climate change is making dry winters more common, those who have worked in the industry for a long time know that weather patterns can fluctuate year to year. The key is to be ready when the snow does come.
