This well camouflaged cache is located just north of a dedicated wildlife conservation area. There's no need to bushwhack or get off the trail, the cache is accessible from the gravel path. Parking on the other hand is going to be a bit of an issue. Parking is available across the street on Stonegate Way although it's an industrial area and can be busy or there is street parking on Sunset Park Place also.
The "Jam" reference in the title is twofold, the city of Ferndale was once referred to as Jam because the city was developed near a log jam on the Nooksack River. The second will make sense once you find the cache.
FTF prize is an unregistered path tag from the 2013 GeoZombie Run.
