Eagle River was a boom town of the copper mining era in the Keweenaw. Copper was discovered in 1845 at the Cliff Range nearby, the so-called "Cliff Lode". The land of the Eagle River community had been leased by the Keweenaw Copper Company in 1843. It was later platted by the Phoenix Company and sold as individual lots. The first postmaster was named on October 24, 1845. It was part ofHoughton County until Keweenaw County was organized in1861. The profitability of the area's copper mines had begun to decline sharply by around 1870.
