This is a link for an Avenza map for the ski trails. To use this, download the Avenza app; the free version is fine. https://www.avenzamaps.com/ Download and save this pdf somewhere on your mobile device, then open the app, click the plus sign and select the pdf file. It will give you a map that shows you where you are on the trail in real time. The free version of Avenza limits you to 3 maps on file, but otherwise seems to be fully functional.
The map below is a jpg version of the map. It is not connected to Avenza, but may help as you plan your skiing activities.
