Grenville Channel
Canada
Grenville Channel is a strait on the North Coast of British Columbia, Canada, between Pitt Island and the mainland to the south of Prince Rupert. It is part of the Inside Passage shipping route, about 45 nautical miles (83 km, 52 mi) long and is 0.2 nautical miles (0.37 km, 0.23 mi) wide at its narrowest point. The Grenville Channel Fault that forms the channel dates back to the Cretaceous Era. Both sides are mountainous and densely wooded, and a linear magnetic anomaly runs parallel to the channel south of 51"30'N.
