Snohomish County Historic interactive overlay maps online

Genealogists and local historians know that maps are often fascinating ways

to trace a family, business, or community history.  Plat map/atlases

(created by Metsker, Sanborn and Kroll and the 1910 Anderson Map Company)

are among the most useful​.  Thanks to the Granite Falls Historical

Society  (Fred Cruger and his crew) these maps have been digitized and we

have this amazing online mapping tool now available online to track

properties and past owners.  It does take some practice and understanding

of the maps but it is now available for you to begin to learn the history

of your property.  The project was created to be a historic asset inventory

<> for

Snohomish County but is available now online for anyone to try out.


I suggest trying option 3 below first to see the properties that are being

 researched for their historical significance.  My experience is that it takes

 a little time to load these files so give it time to load.  Then have fun exploring....

​LOSCHO organizations <> should have a

volunteer or two who are familiar with this to help.  And anyone is

encouraged to contact them to contribute information to the map inventory

to update information.  Appointments are usually necessary.
