ECV Historical Marker Database
Thanks to the good folks at The Historical Marker Database, we have a nice list of 785 ECV markers throughout the United States, including 28 markers attributed to chapter #1864. The database is searchable with a mapping function as well. Take a look through, and if you think one is missing, we’ll see about adding it.
There is also a mobile phone friendly website, which uses your location to show markers near you, and the Field Trip app from Google includes information from HMDB as well.
