   Now add in Donation Land Claims (DLCs) and you really have fun. Before the
Public Lands Survey System (PLSS) established Townships, Ranges, and
Sections (36 per Township, square, 1 mile per side -- 640 acres), sections
where plopped everywhere and in every shape imaginable. That's why you'll
see topo maps of Oregon and Washington with section numbers > 36 and odd
shapes, including slivers. A major mess.
