NEOTECTONICS OF THE CENTRAL ALASKA RANGE: A GUIDEBOOK FOR THE 2005 ALASKA CELL - FRIENDS OF THE PLEISTOCENE FIELD TRIP Edited by Evan Thoms Photo by Sean Bemis View looking east over the northeastern part of the northern foothills of the central Alaska Range. Tatlanika Creek is in the left foreground, Japan Hills are the isolated uplands in the left center, and an east trending ridge of Totalanika Schist is in the lower right. Note the recently uplifted north-trending ridges of Nenana Gravel – the Pliocene foreland basin fill of the Alaska Range — and the beveled surface of the ridge of schist which may either be related to a pre-Tertiary unconformity or to the top of the Nenana Gravel.
