All, I’m working with a patron who is looking for the historic river location(s) between 1905 and 1920 of the Middle Fork of the Willamette River about a mile upstream from the confluence with the Coast Fork. (Township 18 South, Range 3 West, Sections 1 and 12) near the Eugene/Springfield boundary. It appears that Sheet 1 of the following map might be useful. Unfortunately our sheet 1 is missing and Oregon Digital has scanned and made available all but sheet 1. * Title: Oregon, Willamette Valley * Uniform Title: Topography, state of Oregon * Author: Geological Survey (U.S.)<http://alliance-primo.hosted.exlibrisgroup.com/primo_library/libweb/action/search.do?vl%28freeText0%29=Geological+Survey+%28U.S.%29&vl%28716538806UI0%29=creator&vl%281047208650UI1%29=all_items&vl%281UIStartWith0%29=exact&fn=search&tab=default_tab&mode=Basic&vid=UO&scp.scps=scope%3a%28UO%29%2cscope%3a%28E-UO%29&ct=lateralLinking> Oregon.<http://alliance-primo.hosted.exlibrisgroup.com/primo_library/libweb/action/search.do?vl%28freeText0%29=Oregon.&vl%28716538806UI0%29=creator&vl%281047208650UI1%29=all_items&vl%281UIStartWith0%29=exact&fn=search&tab=default_tab&mode=Basic&vid=UO&scp.scps=scope%3a%28UO%29%2cscope%3a%28E-UO%29&ct=lateralLinking> * Contributor: U.S. Geological Survey ; surveyed in cooperation with the State of Oregon. * Publisher: Washington, D.C. : The Survey * Creation Date: 1910] - 1919 * Subjects: Willamette River Valley (Or.) -- Maps<http://alliance-primo.hosted.exlibrisgroup.com/primo_library/libweb/action/search.do?vl%28freeText0%29=%20Willamette%20+%20River%20+Valley+%28Or.%29+--+%20Maps%20&vl%28716538806UI0%29=sub&vl%281047208650UI1%29=all_items&vl%281UIStartWith0%29=exact&fn=search&tab=default_tab&mode=Basic&vid=UO&scp.scps=scope%3a%28UO%29%2cscope%3a%28E-UO%29&ct=lateralLinking> * Description: Relief shown by contours and spot heights.

Also, if you have any other maps which might show the location, please contact me. I don’t believe that the area is considered navigable. I have checked for historical nautical charts and haven’t found any. Kathy Stroud David and Nancy Petrone Map/GIS Librarian Knight Library 1299 University of Oregon Eugene, OR 97403-1299 541-346-3051
