Such rifting as this, resulting from a solution of the basement, has naturally been effective wherever Old Red deposition was left on a limestone base — and these conditions hold true for the northeastern face of the Catskills. Here the relicts of the process bear the marks of great antiquity in notable contrast to those in the northeast. The scarp surfaces of the Catskills are rounded, sloped and deeply eroded, in the Perce mountains they arc sharp and fresh; but there is throughout the moun- tains of Gaspe and their relations to the sea an aspect of newness which constantly surprises the observer.
