3.31: Detail of a Cutoff on the Assiniboine River

This low level photograph was taken 30 years after that in Figure 3.30. It shows the cutoff in figure 3.30 in detail as well as revealing changes that have occurred over the intervening years. The main channel of the Assiniboine is seen in the southwest 1, southeast 2, and northeast 3, and the cutoff occupies the central part of the photo.

The cutoff has been unfilled by sediment and vegetation 4 but some standing water remains 5. The neck of the abandoned channel that was bare sand in 1951 is now (1981) covered by vegetation, including some trees, probably willows (Salix spp) 6. Both within the cutoff 7 and to the west of it 8, meander scrolls can be seen with trees occupying the ridges and grass the swales in between.

The photograph was taken in the spring before the leaf-on stage for some trees as revealed by their shadows 9, but other with round crowns seem to have some foliage 10.
