High-Resolution Plat Maps for Houston, Allamakee and Winneshiek Counties

Plat maps are an excellent resource for local history research. They show where a family lived and farmed, can demonstrate migration over time, and provide context when digging through census records. They can also be used to identify the locations cited in land grant, homestead, and probate records. High-resolution plat maps are clear and easy to read, though some of the links below are watermarked – just scroll the image to get around it.

I’ve included the earliest maps up to 1950 – though maps up to the 2000s are available from Historic Map Works – and have linked to the cleanest images available. If you know of any others – please leave a comment below and share with everyone.
