A Butternut Creek series geocache, along the southern end of the creek, after it passes through the military base.
There do not appear to be any good trails or even paths to GZ for this one -- bushwacking required through swampy ground. Recommend parking at the community centre, crossing the park / sports fields and then into the bush for some 100 m of bushwacking. After getting this one you are encouraged to go a bit north and see the easier Butternut Trail series of caches.
