# Glacial Waterfalls (DD-316)

> Glacial waterfalls form where meltwater from a glacier flows over a cliff or the ice edge. In warm seasons, faster melting makes the falls bigger. Meltwater carries fine ground rock, called rock flour, which gives it a milky look. The footage shows a meltwater river cutting across an ice sheet and pouring over an ice cliff.

## Quick facts

- **DD-316-F01**: Melting ice feeds the falls. _(Write-up · Exhibit A (Meltwater))_
- **DD-316-F02**: Falls grow in warm seasons. _(Write-up · Exhibit B (Seasonal))_

## Write-up

Meltwater can pour off a glacier's edge as a waterfall. Rock flour turns glacial water milky.

1. **Meltwater**: Melting ice feeds the falls.
2. **Seasonal**: Falls grow in warm seasons.
3. **Rock flour**: Rock flour makes water milky.
4. **Ice cliffs**: Water pours over ice edges.
5. **Sediment**: Meltwater carries sediment.

### Transcript

Did you know, glacial waterfalls are a breathtaking natural phenomenon found in cold, mountainous regions where glaciers are present. These waterfalls form when melting ice from a glacier flows over the edge of a cliff or steep slope, cascading down as liquid water. As temperatures rise during warmer seasons, the melting rate of the glacier increases, leading to more substantial and dramatic water flow. Glacial waterfalls often carry sediment and fine rock particles, giving the water a milky or cloudy appearance. NOW YOU KNOW!
