Page, Daniel S, Scheirer, Victoria E. Langerheim, and Mary A. Berger ----------------------------------------------------------------------------- Original edition: Posted on-line in March, 2006 ----------------------------------------------------------------------------- Revised edition: Posted on-line June, 2011 ----------------------------------------------------------------------------- In this revised edition, changes were made to parts of seven of the ten cross sections presented in the original report. Revisions were made to the following cross sections: C–C', D–D', E–E', F–F', G–G', I–I', and J–J'. The parts of the sections revised or extended are highlighted below the sections on plate 1 by red brackets and the word “revised”, or “extended.” Sections not listed above, as well as the interpretive text and figures, are generally unchanged from the original report. Some changes were made to the Description of Map Units on the plate. Unit QTu and unit Ku were combined into one unit, QTKu. Other changes were minor. In the title and throughout the report, the term “ground-water” was changed to one word “groundwater.” The new title had the word "Revised" added. The abstract was updated to reflect the changes. Mary A. Berger was added to the list of authors. Changes within the text were minor, and reflect the previous corrections.
