The foregoing being taken for granted, & the plateau of Woody Mt being assumed as on the same level as the watershed Plateau running N of the Line road N of Porcupine Creek & Eastwards from it; the comparative absence of limestone along the lower levels near the line would tend to prove that the upper plateau was as effectual a barrier as on other grounds it appears to have been, to the passage of ice drifting Southwards with a definite current; or that denudation has gone on much faster on the S. side of the Plateau & cut far into it. (The rapidity of denudation on the Southern as compared with the Northern sides evident on inspection of Nature of Country.)

The alkaline lakes & armless valleys of the Northern Coteau edge along the Traders Road from Woody Mt probably due to blocking of old stream courses by drift during submergence. The rainfall as compared with evaporation, never being sufficient since to enable them to cut through to the North.
