Timing And Paleoclimatic Significance Of Latest Pleistocene And Holocene Cirque Glaciation In The Enchantment Lakes Basin, North Cascades, Wa, Eric L. (Eric Leland) Bilderback

WWU Graduate School Collection

The Enchantment Lakes Basin in the Alpine Lakes Wilderness, Washington, preserves two sets of moraines that record distinct post-Wisconsin maximum advances of cirque glaciers in the eastern North Cascades. Cores collected from five lakes adjacent to the moraines indicate that there were two Neoglacial advances, culminating with the Little Ice Age, and one slightly larger advance that ended coincident with the termination of the North Atlantic Younger Dryas event. The cores show no evidence for an early Holocene advance, in contrast to some other studies in the North Cascades, (e.g., Heine, 1998; Thomas, 1997; Thomas et al., 2000).
