I am a professional cartographer distributing free climbing maps for non-commercial use for Mount Baker, Mount Rainier, and Mount Shuksan. Also, there is a Mount Baker Backcountry map available for download. These maps are provided as geo-spatial PDFs via Avenza Maps (free for iOS, Android, and Windows). With Avenza you can download the map to your cellular phone and see your location on the map even without cellular coverage.
Here is a link to the Avenza download page including more information about the maps: https://www.avenzamaps.com/vendor/2640/shuksan-geomatics
If you want a stand-alone digital copy of any of these maps they can be purchased for $4.99 (plus tax) here: http://www.shuksangeomatics.com/examples.html
Email me with route corrections or GNSS (GPS) tracks and I will update the maps as necessary.
