Fascinating research! Perhaps, I have missed something but have you searched the c. 1897 survey
maps in the Oklahoma State Archives, located on the top floor of the Oklahoma Department of
Libraries in Oklahoma City? Years ago, now retired archaeologist Don Wykoff told me that the
land use patterns on these maps are generally considered to be unchanged from the Civil War;
this, being in regard to research several of us were conducting on Honey Springs. Fields/
agricultural patterns, fence lines, roads/trails and the like had not changed much in the IT by
1897. Also, there are the field notes to these maps. I am also guessing that you have seen the
Chief of Engineers railroad surveys and other reports, part of the Annual Reports of the Secretary
of War. While Google Books probably has these online, GB has the bad habit of not folding out
maps and other plates for full viewing. Sorry for the long reply.
