Overview
- Photos from January 31 show thick ice on cliffs, railings and a boardwalk while powerful flows continue, drawing visitors on both the U.S. and Canadian sides.
- Temperatures plunged to near or below −20°C during the late‑January outbreak, with wind chills and a major winter storm reported across the region.
- Ice accumulated along edges, bridges and surrounding infrastructure as mist and spray froze rapidly in the sub‑zero air.
- The falls’ main flow did not freeze solid due to the sheer volume and velocity of water moving over the brink.
- Reporters say the spectacle should last only while freezing conditions persist, with some coverage placing it within a volatile 2025–2026 winter pattern tentatively linked to a warming Arctic.
