Title: The Origin and Significance of Pitted Outwash
Abstract: Deposits made by glacial streams following a comparatively rapid retreat of the ice from a region of irregular topography buried many isolated ice remnants. When these masses of ice melted, they formed pits in an outwash plain; locally the pits were so abundant that no level surfaces remained. Pitted outwash is compared with other glacio-fluvial deposits that have a somewhat similar topography, with the conclusion that there is danger of confusion with kames. The results of readvances of the ice over outwash before the ice blocks had all melted is discussed. Attention is called to factors that controlled the relative abundance of glacio-fluvial deposits and to the significance of pitted outwash as a criterion of relatively recent glacial retreat before its formation, thus distinguishing recessional from terminal moraines. Examples of the various types of deposits are given.
