在Snag-Klutlan地区划定了两个晚更新世冰川作用的界限。放射性碳测年、漂流物的表面特征和上覆沉积物的孢粉学表明，较老的冰川期（镜溪）的年龄为威斯康星州早期;较年轻的冰川期（麦考利）的年龄为威斯康星州晚期，在c. 13700 BP。Macauley冰川界限内的沉积物的地层学意味着两次冰川之间的冰消作用是最小的。
Two late Pleistocene limits of glaciation were delineated in the Snag-Klutlan area. Radiocarbon dates, surficial characteristics of its drift, and the palynology of overlying sediments imply the older glaciation (Mirror Creek) is early Wisconsin in age; the younger glaciation (Macauley) is late Wisconsin in age and culminated c. 13 700 BP. The stratigraphy of deposits within the Macauley glacial limit implies that deglaciation between the two glaciations was minimal.
