Sourlands GeoPDF

This is a GeoPDF hiking map of the Sourlands Preserve, a Somerset County Park, updated in 2021 with the latest trail changes and the new blazing scheme.. You can print and use this map as any PDF, but it becomes amazing if you install Avenza Maps on your smartphone. Avenza becomes a full-function wilderness GPS, with this trail map as its basemap. And it even works if you lose the cellphone signal.
