Historic sites in Idaho

12 Idaho dossiers sit on ground the record itself recognizes — registered, marked or preserved sites carrying a second file under the plaque. The history is the strong suit here: what the marker says, what the sources confirm and what the legend added afterward. Claims are reported, not endorsed.
