Yosemite’s Horsetail Fall: When a Waterfall Turns into Liquid Fire (for a Few Glorious Minutes)

Horsetail Fall transformed into a fiery “lava waterfall” by the setting sun on El Capitan – one of Yosemite’s most magical natural phenomena.

Dear Cherubs, imagine a waterfall on El Capitan that decides, for a handful of February evenings, to cosplay as molten lava. Horsetail Fall, usually just a seasonal trickle most folks overlook, puts on one of nature’s most dramatic light shows when the setting sun hits it at the perfect angle.

This “firefall” effect turns the cascading water a brilliant orange-red, making it look like the mountain is bleeding fire. It’s equal parts geology, meteorology, and sheer luck—low-key one of the coolest rare events in the U.S. national parks. Bet you’ll want to add it to your bucket list after this.

Why It Happens Horsetail Fall drops roughly 2,130 feet (650 m) down the eastern edge of El Capitan in Yosemite Valley. It’s ephemeral, fed only by snowmelt and runoff, so it often dries up by summer. According to the National Park Service, the glow kicks in during mid- to late February on clear evenings when enough water is flowing and the sun’s position lines up just right. The light backlights the falls for about 5 to 15 minutes around sunset, creating that fiery illusion.

It’s not actual lava or anything supernatural—just refraction and timing doing their thing. Think of it as the universe’s way of reminding us that perfect conditions are rare, and when they align, it’s worth the hype.

The Crowd Scene Every year, thousands of photographers and nature enthusiasts swarm Yosemite Valley hoping for the magic. On peak nights, the viewing area near El Capitan Picnic Area gets packed. The NPS has implemented traffic controls, parking restrictions, and path closures in recent years because crowds got a bit too enthusiastic—spilling into meadows and riverbanks, trampling vegetation, and leaving trash. In 2022, over 2,400 people showed up on one busy night. It’s giving “Instagram made me do it,” but the park is managing it thoughtfully with shuttles and reminders to stay on trails.

Pro tip: No reservations needed for 2026, but arrive early, bring warm layers, traction devices for icy paths, and a headlamp for the dark walk back. Weekdays tend to be less chaotic.

The phenomenon echoes the old artificial Firefall from Glacier Point (where rangers literally pushed burning embers off the cliff until 1968), but this one is 100% natural. First widely captured in color by photographer Galen Rowell in 1973, social media has since turned it into a viral sensation.

Don’t expect perfection every trip. Some years the flow is weak, clouds roll in, or the angle is off. That’s part of the charm—it keeps the experience special. When it works, though, the crowd falls silent as the water ignites, then erupts in cheers. It’s a shared “whoa” moment that feels almost sacred.

Yosemite’s Horsetail Fall isn’t just a photo op; it’s a reminder of how fleeting and spectacular nature can be. Pack patience, respect the rules, and you might witness the mountain set itself ablaze—without any actual flames. Worth braving the cold for, bet.

Unraveling Siberian Permafrost Craters: A Scientific Breakthrough

By, WPS News Arctic Correspondent
Baybay City | April 13, 2026

Scientists have made significant strides in unraveling the mysteries surrounding the massive holes appearing in the Siberian permafrost. These enigmatic craters have long puzzled researchers due to their sudden emergence and extraordinary features. Recent studies have illuminated the formation process of these Siberian holes, indicating that there may be even more craters than previously documented. Over time, certain craters have become filled with water and sediment, further complicating our understanding of this phenomenon.

Situated in a remote peninsula within the Arctic Circle, this area has transformed into a hotspot for the emergence of these colossal craters, which seem to appear explosively in the permafrost. The metamorphosis from a simple hole to a lake is a captivating, albeit dramatic, occurrence in several of these craters. While some holes rapidly flood, others evolve into water bodies at a slower pace, leading to a rich and diverse landscape in the rugged Siberian tundra.

As research continues, scientists are keen to delve deeper into the implications of these Siberian holes for environmental stability. The sudden formation of such craters raises critical concerns about the resilience of the permafrost and the potential hazards they might pose to the surrounding ecosystems. By decoding the secrets of these massive holes, researchers aspire to uncover vital insights into the geological processes that characterize the Siberian region.

Earthquakes, eruptions, and other natural phenomena have always evoked awe, fear and excitement. Ancient cultures would often memorialize these events in myths and legends. More research is being put into which real-life events inspired those stories, including the work of folklorist and historian Adrienne Mayor, whose book “ Mythopedia: A Brief Compendium of Natural History Lore,” explores the connection between event and story.
