The Go Jetters have travelled to Horsetail Fall in the Yosemite National Park. It's a 300m-high waterfall made of melted snow. Once a year the setting sun lights up the water, making it glow like fire for just a few special minutes. This is called Firefall, and if there isn't enough water from the melting snow, Firefall doesn't happen. Unfortunately, Grandmaster Glitch has built a snow princess at the top of the fall and is using an ice machine to stop her melting.
