Colorado Maps
Maps, Atlases & Gazetteers - Maps are an invaluable part of family history research, especially if you live far from where your ancestor lived. Because political boundaries often changed, historic maps are critical in helping you discover the precise location of your ancestor's hometown, what land they owned, who their neighbors were, and more.
The Colorado Highway Department has prepared a series of county road maps. These maps contain more detailed information about man-made features than the geological survey maps. In addition to roads and boundaries, these maps include rural communities, churches, and cemeteries.
