Road Logs

The Montana Geological Society Road Log website is an interactive mapping site that contains digitized routes of historical road logs primarily in Montana. The majority of the road logs were digitized by Montana State University – Billings students.

To use this service:

  1. Simply click on a road in an area you are interested in.
  2. A road log will be highlighted and an attribute table will pop up showing the title, log name, and the year the road log was created.
  3. If the road log overlaps with other road logs, click the right arrow and a new attribute table will appear with another road log in the area you clicked.
  4. If you wish to view the complete road log document, click the “More info” link. A new window will open displaying the road log. From here you can view, print, and download the road log.

This is a mobile friendly interactive map! Open this map on your smartphone with your GPS turned on, and you can access the road logs nearest to you.

Please note that due to the vintage of some of the logs, there may be some level of inaccuracies in the road log lines. They should not be used for navigational purposes.
