The US Geological Survey has been the primary agency responsible for mapping the United States since 1879 and this new curated collection includes the oldest topo maps available from the USGS archives. These old maps were drawn at the scale of 1:62,500 with a coverage of 15 minutes (1/4 degree). About a third of the quadrangles in this map were created before 1900 and over half are older than 1910, with the earliest dating from 1884. A total of seven hundred twelve 1:62,500 quadrangles are included with full coverage of New Jersey, Pennsylvania, Delaware, Maryland, Connecticut, Rhode Island and Massachussets and partial coverage of New York, Virginia and West Virginia.

Unfortunately, about 30 Virginia quadrangles were (apparently) never mapped at 1:62,500 scale and needed to be cropped from 1:125,000 scale maps from the 1880's. Since they are only half the scale, you'll notice a rather crude level of detail when you zoom into these areas.

Generally speaking, the oldest version of each quadrangle was used unless there were problems. For example, some of the earliest maps were incomplete, with large blank areas. Newer maps were used for these.

Original .tif files were downloaded from the Historical Topographic Map Collection, cropped to remove the collar and re-projected as Web Mercator. These source files were processed at a resolution of 4.8 meters/pixel which preserves the full detail of the original USGS 300 dot-per-inch scans.

As you zoom out, the view switches to the oldest available USGS 250k maps (mostly from the 1940's and 1950's). At smaller scales a simple basemap is shown.

Garmin devices do not offer any serious support for raster imagery, so this map is only available in the free boydsmaps web app. Garmin's "custom maps" (.kmz) raster format only supports a total of 100 tiles at 1024x1024 on most devices, however this map would contain over 60,000 tiles if processed in that format!

The boydsmaps web app is compatible with all devices and operating systems, it's free, there's no advertising and no registration. Use it on your phone like a handheld GPS in mobile mode or on your computer with a desktop interface designed for large screens. It's a website, but can also be installed as an app which offers many advantages, especially on phones. In addition to this map there are over 200 more, covering the entire world, including the full suite of maps and imagery from HERE and Mapbox. Many other features like waypoints, live elevation display, weather, radar and more. See the built-in help function for full documentation.
