4468 - Île du Petit Mécatina to Îles Sainte-Marie | Lower North Shore Québec Marine Map

Navigate the wild and intricate coastline of the Basse-Côte-Nord with the unparalleled detail of CHS Nautical Chart 4468. Providing comprehensive coverage from Île du Petit Mécatina to the Îles Sainte-Marie, this chart is an essential hydrographic tool for mariners traversing one of the most remote and navigationally challenging stretches of the Gulf of St. Lawrence. This region is defined by its vast "archipelago of a thousand islands," deep-water sounds, and the rugged granite shores of the Duplessis region.

Chart 4468 features high-resolution mapping of the coastal "inner passage" and the seaward approaches used by regional supply vessels and adventurous cruisers. It offers critical data on depth soundings, seabed composition, and the myriad of rocky hazards that characterize the waters near Tête-à-la-Baleine and the Mécatina bird sanctuaries. Whether you are guiding a commercial vessel through the Passage de l'Île au Michon or a researcher exploring the biodiversity of the Sainte-Marie islands, this official Canadian Hydrographic Service chart provides the accuracy required for safe pilotage in these untamed waters.

Key Features include:

• Extensive Coastal Coverage: Detailed mapping of the Lower North Shore from the Petit Mécatina river delta east toward the Sainte-Marie archipelago.

• Hydrographic Precision: Features high-accuracy depth soundings and contouring essential for navigating narrow channels between granite outcrops.

• Navigational Infrastructure: Clearly identifies remote lighthouse stations, daymarks, and all essential buoyage for the coastal corridor.

• Safety & Hazard Identification: Highlights the "Rochers aux Oiseaux," submerged ledges, and the unpredictable currents of the Jacques Cartier Strait transition.

• Professional Grade: Produced to the rigorous standards of the Canadian Hydrographic Service (CHS) for professional navigation, regional logistics, and GIS spatial analysis.
