The cache is a ways a few hundred yards into the woods. Once you find the cache go check out the Mill River (you should be able to hear it). Near the cache is a popular fishing/swimming hole. Swimming isn't permitted, but that doesn't seem to stop anyone.
Lake Mohegan is located in Fairfield. From either Route 58 or 59 get on to Fairfield woods road. Then turn on to Morsehead Road and follow it all the way to the end. At the end you will enter the Lake Mohegan Cascades area (don't turn into the Lake Mohegan area, which you will pass first). You will drive down a steep hill and the road will turn to dirt. Park at the bottom of the hill.
Finding the Stash:
Find the trailhead with the big stone dedication plaque. Follow that trail due North/East. Once you come across the powerlines follow them up a ways to you see a stone wall. Follow the wall past the 90 degree turn. The stash is tucked deep in the wall and will take a little effort to find.
Note: GPS will bounce around alot even with no tree cover and if anyone can think of a good helper for this cache will happily accept help on figuring out
Replaced with Corporate America Cache, Redux due to original owner of both disappearing from caching
