About
Cascadyas is a field atlas of the world's waterfalls, built entirely on open scientific data.
For each waterfall you will find how high it drops, an estimate of the water it carries month by month and the best months to go, the river profile and the valley from the 30 m Copernicus relief, the weather from 30 years of NASA data, what each year was like from 2020 to 2025, and what is around: paths, viewpoints, parking, swimming spots and towns.
Everything is an average or a count from a public dataset — never a forecast, and never an opinion. Sources and licences are listed on the data sources page.
