The Sanborn Map Company produced fire-insurance maps starting in1867. The fire insurance maps show building footprints, building material, height or number of stories, building use, lot lines, road widths and water facilities. The maps also show street names and property boundaries of the time. This collection of maps is historically significant as it is sometimes the best detailed map of a town or city dating from the mid 1800s. This Fire Map of Ida is dated 1921 and is hosted by the Library of Congress. Click on the map below to go to the map at the LOC.
