It became clear that extensive areas of either very old mapping, or only broad reconnaissance mapping undertaken in preparation for the State Geologic Map (Isachsen, unpub. maps), lay in the southern half of the Adirondacks. This situation made the area attractive to new workers interested in geological mapping and structural synthesis, and resulted in numerous new investigations (de Waard, 1962, 1964; Walton and de Waard, 1963; de Waard and Romey, 1963, 1968; McLellahd, 1969, 1972, 1978; Nelson, 1968; Letteney, 1969; Glennie, 1973; Geraghty, 1978).</p>
