Header: A RIVER EMERGED FROM UNDER A GLACIER
Text and illustrations from top to bottom:
- [Depicted in stylized scroll with illustration of a steam shovel in gravel pit] The Record: There are several old gravel pits in the Arboretum.
- Interpreting the record:
- 1) A river running under a glacier is confined to a narrow channel, and is, therefore swift. Because of its swiftness it can carry gravel.
- 2) When such a river comes out from under the ice it spreads out and slows down. Slow moving water can carry only fine material. Therefore the river dropped its heavy material.
- 3) When men found these places they dug the gravel out.
