四个冰碛系统被确认在该地区。最古老的沉积在边缘的主要出口冰川约600米a.s.1当地科里冰川在苏伦和Itidlirn山谷分别显示三个和两个冰碛系统，其中部分已超过侧冰碛。 对四个单元上的卵石风化程度和卵石边缘圆化的研究允许Itidlirn和苏龙谷之间的相互关联。风化率被用来初步确定冰碛物的年代如下：出口谷冰川的侧冰碛物，43 000±年;苏龙谷的第1期科里冰碛物，35 000±年;第2期科里冰碛物，23 000±年;最年轻的科里冰碛物（第3期），12 500±年，这是从邻近山谷的风化研究中确定的。
Four moraine systems are recognized within the area. The oldest was deposited at the margin of a major outlet glacier about 600 m a.s.1 Local corrie glaciers in the Sulung and Itidlirn Valleys show three and two moraine systems respectively, which in part have over-ridden the lateral moraine. Studies of the degree of boulder weathering and the rounding of pebble edges on the four units allows cross-correlation between Itidlirn and Sulung Valleys. Weathering ratios are used to tentatively date the moraines as follows: lateral moraine of the outlet valley glacier, 43 000± years old; Phase 1 corrie moraine in Sulung Valley 35 000± years old; Phase 2 corrie moraines 23 000± years old and the youngest corrie moraines (Phase 3) 12 500± years old, as determined from weathering studies in adjacent valleys.
