The not-always-annual natural phenomenon known as the "firefall" at Yosemite National Park's Horsetail Fall is happening through this weekend.
The event, which SFist last took note of via a flurry of Instagrams in 2016, occurs when the sun sets at a particular angle during the middle two weeks of February. But in order for the spectacular glowing effect to happen, skies have to be clear and there has to be enough water running over the falls — so for several years during the drought there was no "firefall."
Central Valley-based photographer Vaché Geyoghlian captured the images below on Tuesday (hit the arrow at the right for a close-up).
ABC 7 reports that heavy snow in Yosemite and a list of parking and stopping restrictions means that getting to the perfect vantage point to see the "firefall" could be "tricky." Visitors will need chains for their tires, as well as gear to help them hike through snow.
Below, several more images captured in the last week by photographers at Horsetail Fall.
