How we calculate this

This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.

Estimate from Open-Meteo daily temperatures at the falls, the LiDAR-measured facing direction, and the nearest stream gauge. It is a likelihood, not a report from the trail.

The Terrain, Seen by LiDAR

Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.

The laser survey finds one clean step here: roughly 257 feet of drop concentrated at the brink. Elevation at the pin is about 442 feet.

The whole reach is steep: about 263 feet of descent in the 500 feet above the falls and another 164 feet in the 500 feet below. The falls face east and catch soft morning light.
