The Ice Age Floods are the rare earth-science story that has everything at once: planetary scale, deep time, vivid landforms, and a fifty-year scientific argument with a clear winner. The immersive captures turn all of it into something a student can walk through.
Ten times every river on Earth is an abstraction until you stand on the floor of the waterfall it made.
Cosmogenic dating put a real number on the floods. Students see how we know what we know.
An erratic’s elevation is a measurement. The valley is a dataset you can read with your eyes.
Bretz was rejected for fifty years. The story of how he was vindicated is the scientific method itself.
The big story, told simply: a giant lake, an ice dam, a flood you could see from space. Virtual walks and a reconstruction to watch.
Match landforms to the forces that made them. Use erratics and ripple marks as evidence of flow direction and depth.
Cosmogenic exposure dating, the Bretz controversy, and how a scientific consensus actually changes. Reading primary field notes.
The full field record, the published chronology, and the source materials behind every claim on the site.
Walk a real trail on the classroom screen , no bus, no permission slips, any weather.
Spin a flood boulder, find the striations, measure it , the rock in your hands, on a tablet.
A short rendered film of the dam failing and the flood running , the hook that starts the unit.
Printable worksheets and guides that work offline and travel to a visitor-center kiosk.
One erratic, one number, one big idea: if an iceberg carried this rock to 327 feet, the floodwater had to be at least that deep. Do it across a dozen boulders and you’ve mapped a flood.
Open the specimen used in this lesson →Mapped to NGSS earth-science and science-practice standards , landforms and surface processes, the history of planet Earth, and analyzing and arguing from evidence.
The curriculum hub is a Phase 2 build , and it should be shaped by the teachers who’ll use it. Tell us your grade, your standards, and what would actually help.
