I have created a Garmin GPS map of snowmobile trails in North Dakota. Data to make the map was obtained from Snowmobile North Dakota and includes the following trail systems.

Southern Valley
Sheyenne Valley
Snowtrails
Sargent County
Red River North
Red River South
Sakakawea
Peace Garden
North Central
Northeast
Missouri Valley
East Central Valley
Little Missouri
Mayville-Portland
Lake Region

The map installs into Mapsource where you can then select it for upload to your Garmin GPS unit. The map has a transparent background so your basemap or any detailed map you upload with the trail map will show through. The trails will appear as a white line with red border on late model color units and a red line on older units.

Here is an example of how the trails will appear on your GPS screen.
(trail map was uploaded along with US Topo - Walhalla area shown)
