1993 Map of Farallon Islands

USGS Topo · Published 1993

About this map

The Farallon Islands emerge from the depths of the Pacific at the edge of the Continental Escarpment, serving as a critical maritime landmark west of San Francisco. This topographic-bathymetric study, edited in 1993, highlights the stark isolation of the Farallon National Wildlife Refuge and Wilderness, where islands like Southeast Farallon Island and Maintop Island provide refuge far from the mainland. The inclusion of a Coast Guard Reservation underscores the strategic importance of these rocky outcroppings for regional navigation.
