..., and such winds may have greatly influenced eolian sedimentation. In Nenana River valley and in most of adjacent Teklanika River valley, the entire 1- to 2-m-thick eolian cap is postglacial in age, and the beginning of loess deposition coincides almost exactly with rapid recession of late Wisconsin ice...

Of prime concern was the identification of outwash derived from the Healy (early Wisconsin) and Riley Creek I (late Wisconsin...

...) In the central part of the basin, the Nenana River area, changes in channel morphology, stream profile perturbations, and uplifted Pliocene-Pleistocene erosional surfaces coincide with a series of east-trending anticlines. We interpret these folds as part of an active Neogene thrust belt that forms the foothills...

...) to identify two main lineaments, inferred as faults. The Nenana sedimentary basin underlies the physiographic low‐lying region of Minto Flats, through which the Tanana River flows (Fig.  2 ). The Nenana basin is approximately 90 km long and 12 km wide, with a maximum depth of 8 km ( Van Kooten et al...
