See familiar places under hundreds of feet of water.
The app turns an abstract geologic event into an explorable landscape-scale model.
Raise and lower the lake
Move through different lake stages and see which valleys, benches, and communities would have been submerged.
Explore the landscape around you
Use maps and location-aware views to connect present-day terrain with the former lake basin and flood history.
Understand the flood story
Use concise geologic explanations to connect the ice dam, lake cycles, shorelines, and catastrophic outburst floods.
A learning and visualization tool, not a precision hazard model.
- Modern elevation data
- Mapped Missoula Ice Age Floods Simulator shorelines and geologic interpretation
- Published regional Ice Age flood research
- Location services on your device
- The simulation simplifies a complex and repeatedly changing glacial-lake system.
- Displayed shorelines and water depths are interpretive approximations.
- The app is educational and is not intended for navigation, engineering, or hazard forecasting.
Common questions.
Is the app free?
Yes. Missoula Ice Age Floods Simulator is a free educational app.
Does it show the exact lake at one single moment?
No. The lake changed repeatedly through time, and the simulator presents an interpretable range of water levels rather than one definitive snapshot.
Is it available on Android?
