About this map

Patos Light stands at Alden Point, marking the northwestern edge of this maritime landscape within the Strait of Georgia. The archipelago is characterized by the distinct, curving shapes of the Sucia Islands, where the sheltered waters of Echo Bay are framed by the narrow ridges of North Finger Island and South Finger Island. This 2011 survey captures the intricate shoreline of Sucia Island, revealing the landforms of Lawson Bluff and the nearby Cluster Islands.

Navigational hazards and maritime boundaries are prominent, from the submerged hazards of Clements Reef to the Ketchikan-Bellingham passage. The proximity of Patos Island to Boundary Pass underscores the strategic location of these northernmost reaches of Whatcom County. Small outcrops like Little Patos Island and Harnden Island complete this detailed study of the San Juan archipelago's northern periphery.
