Following Bouchard (1974) and Rampton (1982), the deposits can be separated into four general units: 1) lower marine clay, 2) "mixed" preglacial sediments and peat, 3) marine clay, and 4) postglacial lacustrine, terrestrial, colluvial, and beach sediment.

In the report on eastern New Brunswick, northwest Nova Scotia, and part of Prince Edward Island, Chalmers (G-1892a, b, 1893, 1894, 1895a, b) again devoted space to preglacial denudation, the topic arising from the physiography of the Cobequid Mountains, where evidence pointed to the same conclusions as reached for the Caledonia Hills in the previous report.
