从上级湖恢复的五个核心的粒度剖面显示，粒度随埋藏深度增加的冰后期冰川接触。研究结果反映了9500年至6500年前底流速度和相应风速的大幅降低。
Profiles of grain sizes in five cores recovered from Lake Superior show that grain size increased with burial depth to the postglacial-glacial contact. The results reflect a substantial reduction in bottom-current velocity and the corresponding wind velocity from 9500 to 6500 years ago.
