2023 Map of Lopez Pass

USGS Topo · Published 2023

About this map

Decatur Island and the southeastern corner of Lopez Island anchor this maritime landscape, where the waters of the Salish Sea meet the Rosario Strait. This modern survey details a complex archipelago of smaller landforms including Center Island, Colville Island, and Fortress Island, many of which fall under the protection of the San Juan Islands National Wilderness. The map reveals how local transportation adapts to the island geography, featuring the Decatur Shores Airport and Center Island Airport alongside a network of coastal roads like Lopez Sound Rd and Mackaye Harbor Rd. From the prominent heights of Chadwick Hill to the sheltered waters of Mud Bay and Hunter Bay, the map documents the established boundaries of the San Juan Islands National Monument, illustrating the balance between private island life and federal conservation.
