Firewall is one of Yosemite’s national park most amazing spectacles. It happens every year, from the middle of February until the end of the month. Orange light falls onto the waterfall. And thanks to the sunset, it looks like firewall.
The phenomenon is mostly visible in the evening hours. You need clear sky to see how the waterfall flows. If it is foggy or cloudy, you cannot see the effect.
The phenomenon is natural, but it looks like a human hand lights up the torch and the fire waterfall. Some experts believe that next year, there might not be a firewall. Their explanation is the global warming.
By then, enjoy in the firewall of 2019.
