Origin and Environmental Significance of Large-scale Patterned Ground, Donnelly Dome Area, Alaska
Large-scale patterned ground in the Donnelly Dome area of central Alaska consists of polygons 25 to 46 m in diameter bounded by shallow troughs 1 to 2 m wide that form the sides of the polygons. The troughs are underlain by wedge-shaped masses of sediments that extend downward 2 to 3 m. Texture of the sediments of the wedges is distinct from that of the poorly stratified glacial outwash gravel that the wedges transect. Sediments of the wedge vary texturally along the strike and vertically within a given wedge. The coarsest material in the wedge is about 75 mm in diameter, which is the same size as the coarsest material in the outwash. The fine material in the wedges is silt, the same as that...
Eva Interglaciation Forest Bed, Unglaciated East-central Alaska
The ancient, boreal Eva forest forms the centerpiece in this evaluation of the time and nature of the enfironment during an interglaciation. This title brings together results of exmaination of hundreds of loess exposures, when loess faces were still frozen in gold-mining excavation, and data on the character and age of the deposits from fission-track dating of tphra, paleomagnetism of the loess, thermoluminescnece dating of loess, and radiocarbon dating by liquid scintillation. Dendrochronology studies of trees are compared to those from trees of the modern boreal forest.
