Cache is located just down river of the RR crossing. Years ago the Atlantic and Lake Superior Railroad had a spur line here to access the Porcupine Mtn mines. Little remains but concrete foundations. Use the Bonzana falls parking lot. Just past the lot there is a trail along the river which will get to the cache. But... 1 you will have to leave the trail to find the cache near the end, and... 2.. in high water levels (spring) trail may be underwater.
