New Mexico has marked its roadsides since 1935, one of the oldest programs of its kind in the country, and the Historic Preservation Division publishes the marker texts in a spreadsheet of its own. Three hundred and ninety-eight of those markers now have permanent pages at TreeAlive, each placing the Division's text, word for word, on georeferenced maps from the eras it describes. Most sit on the Division's own coordinate; where its spreadsheet gives only a highway and a mile marker, or describes the spot in words, the pin is ours, resolved on the state's milepost and road data and marked approximate. The Division says plainly that its list may be out of date and that it does not know where every marker now stands, and these pages say so too: a marker listed here may have moved or may no longer stand.

TreeAlive maps family trees. When a visitor's ancestors lived in New Mexico, the markers standing near those places surface automatically alongside their family's journey:
Las Vegas · under a mile from where the family lived in the 1880s · what this marker records spans 1846 to 1893, overlapping the family's years here
When a marker stands near a place in your own tree, you have a personal reason to go see it. Open the live demo tree, choose the Crossings tab, and turn on Historical Markers to see the experience working (the demo family’s markers are in Pennsylvania; a New Mexico family sees New Mexico’s).
