My basic bible for all PLSS queries is C. Albert White, _A History of the Rectangular Survey System_ U.S. Department of the Interior, Bureau of Land Management (Washington: GPO, nd [1982?]). Sup. of Docs. no. I 53.2:Su7/2 This covers all the technical details you ever wanted to know about the surveys, although you may have to dig around a bit. Matthew Edney [log in to unmask]
