Sugar Island and the international boundary between Michigan and Ontario define this 2014 survey of the upper Great Lakes waterway. The map illustrates the complex hydrography of the Saint Marys River as it splits around landmasses like Neebish Island and Rains Island. Small interior drainages such as Anderson Cr, Shewfelt Cr, and Coulters Cr feed into the larger river system, which serves as a critical maritime corridor. The settlement of Homestead anchors the northwestern portion of the sheet near Harwood Point. Land-based navigation is marked by local routes including S Homestead Rd and S Rains Island Rd, while topographic landmarks like Moon Hill and river features like Johnson Point provide orientation within this borderland environment.
