News

The natural phenomenon that makes it appear that lava is flowing over a cliff at Yosemite National Park is back.

The sight draws hundreds of visitors to the california park each night.

The natural phenomenon happens at horsetail fall when the setting sun causes light to hit the water at just the right angle. It makes it look like lava is flowing over a cliff. The firefall only happens in February and lasts for just a few days.

It is expected to dissipate this weekend.
