AEG Puget Sound and Nisqually Chapters hosted a geo-hiking field trip in Cougar Mountain Regional Wildland Park in September 2021. For those unable to attend, or for those wishing to revisit the stops from the trip, the field guide and maps are linked below.
The maps are geo-PDFs, meaning you can import them to smartphone apps like Avenza (free!) to see your GPS location on the map!
