Reading the Missoula Ice Age Floods Simulator timeline

The simulator presents the lake as a changing system rather than one fixed shoreline.

• Move through water levels slowly and watch how connected valleys change.
• Compare modern communities and landforms with former inundation.
• Use interpretive notes to connect the ice dam, repeated lake cycles, shorelines, and outburst floods.
• Treat displayed depths and shorelines as educational approximations.

The simulation is not intended for navigation, engineering, or modern flood-hazard forecasting.
