In the Letchworth State Park, north of the state of New York, impressive ice volcanoes over 25 feet tall (about 7.5 meters) have formed. These bright structures, known as “ice volcanoes,” are generated by a gravity-fed fountain system that propels water upwards with great pressure.
The water does not freeze immediately, but as it falls onto surrounding surfaces in below-freezing temperatures, it solidifies and creates a cone of thousands of icicles. This phenomenon, documented since the 19th century, has become one of the main winter attractions of the park.
System Operation
- Water flows from an elevated reservoir into a chamber that compresses the air.
- The pressure propels the water vertically through a spout, creating a powerful fountain without the need for pumps.
- As it falls, the water freezes and forms the conical structure.
- The cone continues to grow as long as the fountain is active and temperatures remain cold.
Extreme Weather Context
The phenomenon coincides with a polar wave that hit the northeastern United States. Over the weekend, the wind chill dropped between -10 and -15 degrees in cities like New York, Boston, and Philadelphia, and in some locations, values close to -30 degrees were recorded.
In Watertown, New York, the temperature dropped to -36 degrees, the second coldest February in the state’s history. The National Weather Service issued extreme cold warnings for more than 43 million people, due to northwesterly winds linked to the polar vortex.
Human Consequences
The cold wave left at least 18 people dead, as confirmed by New York City Mayor Zohran Mamdani. Five deaths were directly related to hypothermia, and in several cases, alcohol or methamphetamine consumption was detected, factors that worsened the effects of the cold.
Authorities opened 60 new shelter spaces, an additional warming center, and deployed mobile units with doctors and essential resources to assist homeless people and vulnerable neighbors.
Forecast and Persistent Risks
Although temperatures are beginning to normalize and values above average are expected in the Interstate 95 corridor, risks persist such as:
- Snow accumulations.
- Falling ice.
- Frozen ports affecting economic and logistical activity.
The Letchworth ice volcanoes are a natural spectacle that reflects the interaction between hydraulic engineering and extreme weather. However, behind the beauty of the phenomenon lies the devastating impact of the polar wave, which has claimed lives and forced the reinforcement of emergency measures in New York and other regions of the northeastern United States.
