1985 Map of Sugar Mountain

USGS Topo · Published 1986

About this map

Isle Royale National Park is defined here by its striking parallel topography, where the massive Greenstone Ridge and Minong Ridge run southwest to northeast across the island. This mid-1980s data highlights the physical remnants of the island's brief copper mining boom, most notably at the Island Mine and its associated Cem near the shores of Siskiwit Bay. The map captures a landscape shaped by these steep ridges and the drainages between them, including Washington Creek and Grace Creek flowing into the western bays. Interior water bodies like the expansive Lake Desor and Lily Lake sit perched among the elevations of Mount Desor and the quadrangle's namesake, Sugar Mountain. Extensive wilderness trails, such as the Minong Trail and Feldtmann Ridge Trail, connect these remote landmarks for modern backcountry navigation.
