Cosmogenic surface-exposure age limits for latest-Pleistocene glaciation and paleoclimatic inferences in the American Fork Canyon, Wasatch Mountains, Utah, USA
Abstract The Wasatch Mountains of north-central Utah bordered the eastern shore of Lake
Bonneville and were occupied by numerous valley glaciers during the latest Pleistocene.
Stratigraphic and morphostratigraphic observations near the mouths of Little Cottonwood
and Bells Canyons reveal that glaciers in these two valleys began constructing terminal
moraines before Lake Bonneville reached its maximum shoreline elevation at about 19-17
cal. ka. Although the chronology of the lake highstand is well constrained by numerous …
