Triangulation Stations |
Some of the triangulation stations used in land surveys are included on the Department of Transportation County Maps, which were the source of the Detailed Township Maps. These are of little interest to most researchers, but in some cases they provide the only surviving clue as to the location of an early settlement. |

Want to find even more information about one of these Triangulation Stations? Just consult the topographical maps. Note the nearest searchable landmark shown on the Detailed Township Map (usually a Town) and its distance and direction from the Triangulation Station. Use that landmark to find the appropriate topographical map, then center your display near the Triangulation Station and select the most detailed scale -- sometimes, you'll find the named benchmark. Sometimes, just the BM symbol. With luck, though, you'll spot something (perhaps a church or a cemetery) bearing that name within a 5-mile radius. |
