3868 - Port Louis to Langara Island Nautical Chart

The Northwest Frontier: 3868 - Port Louis to Langara Island

Navigate the remote and powerful waters of northern Haida Gwaii with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3868 is the definitive 1:72,921 scale "road map" for mariners, providing the wide-area situational awareness required to transit the rugged western and northern shores of Graham Island, from the protected inlets of Port Louis to the strategic gateway of Langara Island.

Precision for Offshore Transit and Dixon Entrance Approaches

The northwest corner of Graham Island is a dynamic maritime environment where the Pacific Ocean meets the Dixon Entrance. CHS Chart 3868 provides the "ground-truth" data required for safe offshore pilotage:

• Strategic Coastal Coverage: Features a continuous view of the coastline, including vital landfalls such as Frederick Island, Lepas Bay, and Chanal Reef, identifying safe routes through high-swell environments.

• Langara Island & Parry Passage: Detailed bathymetry for the approaches to Langara Island, a premier destination for commercial fishing and eco-tourism, and the western entrance to Parry Passage.

• Hazard & Shoal Intelligence: Explicitly marks significant offshore dangers, drying rocks, and the nature of the sea bottom (rock, sand, or mud) across this geologically active and weather-sensitive region.

• Essential Navigational Aids: Provides precise locations for coastal lights, beacons, and elevations, vital for situational awareness when transiting the foggy and cloud-prone Pacific horizon.

The Professional Standard for Northern Haida Gwaii Safety

As the primary navigational resource for vessels transiting the outside of the archipelago toward Alaska or the northern mainland, the reliability of Chart 3868 is paramount. Specifically designed to meet the rigorous requirements of marine navigation, this official CHS chart delivers the accuracy and detail needed to traverse the northern frontier of British Columbia with total confidence.
