In 1913, the Great Northern Copper Company based out of North Dakota opened a copper mine. Although the town had high hopes for the mine, it amounted to little. In 1917, after only a few loads of ore were pulled out, the price of copper plummeted and the mine was shut down. The entrance to the mine has since been sealed shut with concrete, however, some remnants of the mine remain at Sea Breeze Park for visitors to view.
