15 The primary image on the Indiana Geological Survey's 2013 calendar displays both relict and modern-day stream channels of the East Fork of the White River just south of the confluence of the Driftwood and Flatwood Rivers near Columbus, Indiana. Cartographers at the Indiana Geological Survey created this image using the new statewide LiDAR elevation and intensity data with Esri ArcGIS software. A 21 by 33 inch full-color calendar printed on heavy poster paper is available for $5 from the Indiana Geological Survey Bookstore.
