Arboretum Landscape Teaching Aid Series: The Great Ice Sheet (3.19496)
Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material shows how the Arboretum Hills were pushed from Canada and Wisconsin.
Header: THE GREAT ICE SHEET brought THE ARBORETUM HILLS from Canada to Wisconsin
Text and illustrations from top to bottom:
- [Depicted in stylized scroll with an illustration of a body of water between two hills] The Record: The Arboretum hills are made of unsorted clay, sand, gravel and boulders.
- Interpreting the record:
- 1) Ice-deposited material is an unsorted material [arrow pointing right to illustration of ice-deposited material] Water-deposited material is sorted into layers [arrow pointing right to illustration of water-deposited material] The Arboretum hills are made of material dumped by the melting ice.
- 2) Granite boulders are found in this material. No granite bed-rock is found within 200 miles of here.
- 3) Rocks frozen into a glacier are flattened and scratched like this [arrow pointing left to illustration of a rock] (see rock at end of table) Water-borne rocks are rounded and smoothed.

Arboretum Landscape Teaching Aid Series: A River Emerged From Under A Glacier (3.19497)
Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material shows the origin of gravel pits at the Arboretum.
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.

Arboretum Landscape Teaching Aid Series: A Fence Long Gone Marked A Boundary (3.19498)
Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material shows how a fence once marked a boundary through a forest.
Header: A fence (long gone) marked a boundary through a forest (long gone)
Text and illustrations from top to bottom:
- [Depicted in stylized scroll] The Record:
- 1. A long row of trees: red oaks, white oaks, and ironwood [an illustration of a row of trees]
- 2. the soil profile on both sides of this row [arrow pointing right to illustration of a cross-section of soil]
- Interpreting the record:
- 1) Because red oaks and ironwoods belong in rich (mesophytic) woods, and
- 2) because a thin layer of black soil on top of clay is typical of forests in this area (but not of prairies) and
- 3) because there would have been forest-margin trees, like hawthorn, if this fence had edged a forest - We read the record as above [arrow extending upward to header]
