In 1845, a large amount of silver was discovered in this little town but efforts to mine the silver were near impossible due to various weather conditions and tumultuous water of Lake Superior. They fought against storms, tidal waves, and ice surges all to no avail until decades later, the miners were finally able to retrieve the silver worth $3 million by building a breakwater of rock and concrete that was able to hold back the raging water. In 1883, all operations ceased due to lack of funds for fuel to keep the furnaces going as well as water-filled shafts.
