Abstract

A swampy very low-relief drift terrain along the medial zone of the northern Long Range Mountains passes outward into fresh glacially eroded bed rock of low to moderate relief with abundant evidence of radial overflow from a late-glacial icecap. A discontinuous belt of moraines and concentrated boulders delineates a stillstand or readvance after the icecap had retreated entirely to the upland and was about 50km broad. Relatively thick till and an abundance of boulders in the medial low-relief zone suggest that after further contraction to 10 to 15km wide, the icecap contracted rather slowly. -Author
