| Abstract: | In southern Michigan, a multiglaciated area of thick drift, regional differences in the altitude of the buried bedrock surface control the direction of major drainage lines and facilitated some stream reversals during deglaciation. Furthermore, individual bedrock valleys, though deeply buried, may influence surface forms in a fashion that induces transverse relationships between river courses and morainal trends. Apparently one or more ancestral glacial landscapes were influenced by the bedrock surface and are also reflected in the present topography. Such palimpsest landscapes may be more widespread in glaciated terrains than have generally been recognized. |
