Motor Vehicle Use Maps

Driving conditions on National Forest roads are much different than on city streets or state highways. Forest roads range from two-lane paved roads to dirt tracks winding through the brush. Most National Forest roads are single-lane, gravel, low-speed roads.

Some roads are closed to protect wildlife or because they are not safe for travel. You can find out about road closures by using a Motor Vehicle Use Map (MVUM) and by calling the local ranger station.

The Siuslaw National Forest MVUMs show the roads, trails, and areas of the forest that are open to motorized vehicles, as well as any seasonal restrictions applied to those routes and areas.

MVUMs also identify what vehicle classes (highway-legal vehicles and off-highway vehicles) are allowed on routes and in riding areas, where dispersed camping is permitted, as well as general travel rules and regulations. Routes not shown on the MVUM are not open to motor vehicle travel. Routes designated for motorized use may not always be signed on the ground, but will be identified on the MVUM.

When traveling on the Siuslaw National Forest, it is the operator’s responsibility to drive cautiously and use a current MVUM showing National Forest System roads, trails, and areas designated for motor vehicle use. Maintenance of designated roads and trails will depend on available resources and many may receive little maintenance. By your participation, you voluntarily assume full responsibility for damages, risks, and dangers. 

MVUMs are updated annually. The map is a black and white map with no topographic features. It is best used in conjunction with a Forest Visitor Use Map, Ranger District Map, or other topographic map. 

Where can I get the maps?

Paper MVUM maps are available for free at Siuslaw National Forest offices.

Geospatially enabled PDF (geoPDF) maps are available for download below. When you open a geoPDF, you will see your location in real-time, can find locations using geographic coordinates, measure distances, and add location markers. You can also copy coordinates to the clipboard for use with a web mapping service.

To use a geoPDF on your computer you must have Adobe Acrobat Reader DC, which can be downloaded for free. Once the map is open in Acrobat Reader DC you can view the geospatial measuring tools by choosing Tools > Measure.

You can also view these maps on any GPS-enabled mobile device using an app such as Avenza Maps (we recommend carrying a paper map as backup). PDF Maps enables you to download maps for offline use on your Apple iOS or Android smartphone or tablet. Use your device's built-in GPS to track your location on the map. You can also plot and record information about locations, import and export placemarks, measure distance and area, and even plot photos.

In order to use the MVUM PDFs you will need to use an overview locator map (p. 6 of each MVUM) to determine which map page you want to look at. Locator maps divide the MVUMs into a grid using Township and Range, which is a system used by cartographers and land surveyors to organize maps. Find the area on the locator map you’re interested in and note the township and range (indicated by an alphanumeric label, such as T2S R11W) then find the corresponding map in the MVUM.
