The coverage of the shorelines starts approximately 8 km northeast of Ashland and extends for about 40 km to approximately 3 km east of the Bad River mouth. The shorelines were derived from land survey maps, topographic maps (USGS), and aerial photographs. The data set includes 10 shorelines for the years 1852, 1934, 1939, 1953, 1963, 1979, 1986, 1992, 1999, and 2013. Detail in the initial years of the shorelines (1852, 1934) may appear to be coarser having been hand drawn. Following 1939, all the shorelines were...

Large amounts of waste material from copper mining, locally known as “stamp sands,” were dumped into the lake in the early 20th century, with wide-reaching consequences that have continued into the present. Mapping was focused offshore of the town of Gay on the Keweenaw Peninsula of Michigan, where ongoing erosion and re-deposition of the stamp sands has buried miles of native, white-sand beaches. Stamp sands are also encroaching onto Buffalo Reef, a large...
