Abstract
The Winegar Phase of the Wisconsin Glaciation produced a band of hummocky glacial topography in northern Wisconsin. Some hummocks are composed of flow till and somewhat sorted till-like debris-flow sediment. These hummocks formed when ice melted beneath a cover of debris that flowed to its present position. Other hummocks contain interlayered lodgement and meltout till, flow till, debris-flow and slopewash sediment, lake, and meltwater-stream sediment. These hummocks formed where sediment was stacked near the ice margin. In other hummocks till and supraglacial debris-flow and slopewash sediment deposited during the Winegar Phase form a thin veneer over older meltwater-stream sediment. These hummocks formed when ice buried in pre-Winegar Phase stream sediment melted, and the overlying sediment collapsed. ?? 1993.
