Late Pleistocene and Holocene glaciation of the Fish Lake valley, northeastern Alaska Range, Alaska
Abstract We reconstructed a chronology of glaciation spanning from the Late Pleistocene through the late Holocene for Fish Lake valley in the north‐eastern Alaska Range using 10 Be surface exposure dating and lichenometry. After it attained its maximum late Wisconsin extent, the Fish Lake valley gla...
