1993 Map of Machias Seal Island South
USGS Topo · Published 1995About this map
Machias Seal Island sits at the northern edge of this maritime study, which focuses primarily on the open waters of the Atlantic Ocean and the Gulf of Maine. Based on imagery from 1990 and field-checked in the early 1990s, the map highlights the isolated nature of this marine environment. A significant geopolitical note in the margin indicates that a portion of the United States-Canadian boundary in this area was in dispute at the time of publication and is therefore not shown. The entire area depicted lies below 20 feet in elevation, emphasizing the sheet's focus on the sea and its immediate coastal features rather than terrestrial settlements or infrastructure.
