We now offer the ability for you to do just that using your mobile device. Introducing the Avenza Maps application.

Once the application is installed, you will need to load a map of the area you plan to visit. The first time you open Avenza Map it will ask you to “sign in”; however, you don’t need to sign in to use the application.

  2. Download A Topographic Map: From your web browser on your mobile device, pick this link to open a list of Skagit County’s Topographic Maps.

At the bottom of the sheet is an index with the sheet names.

  3. Viewing Maps: While you are still in the “Avenza Map” application, pick “My Maps” in the lower left corner of the application followed by picking the map you just downloaded. The map will open and, if you are within the map extent, a blue dot will show up where you are standing (your GPS position). The application also has some fun tools you can access in the lower left corner; including, adding way points.

Have Fun and Be Careful. These maps are for reference only. They are designed to give the user a general idea of where they are in the wilderness. They are not designed to show hazardous areas or other dangers associated with using maps.
