A linen mill was built back at ground zero in 1810. It produced sail duck for boats and soon went out of business as the war of 1812 ended and the need for sail duck diminished. The old mill dam is all that remains today of the original mill.
The cache is regular size. There is no need to tear things apart at ground zero. Indeed, the cache should be partly visible and is meant to be an easy find. Please place everything back as you found it. Best of luck and have fun!
