Oblique aerial view of the Kennicott Valley, a major glacial valley in Alaska’s Wrangell Mountains. Lower ablation zone of the Kennicott Glacier is shaded blue, and adjacent white spruce forest is shaded red. Forest boundaries are dictated by the modern extent of the glacier, below, and the treeless alpine zone, above. For a study of the characteristics of this white spruce forest, the landscape was stratified by landform type: LPm = Late Pleistocene glacial moraines deposited during the Last Glacial Maximum; Qda = Quaternary depositional apron consisting of colluvial debris and glacial meltout tills; Hmx = Holocene McCarthy Creek terraces left behind by incision of a small glacial stream; and LHgm = Late Holocene glacial moraines exposed by recent Little Ice Age retreat of the Kennicott Glacier.
