Region Overview & Navigation
Blackstone Bay is a dramatic, high-energy fjord located just southwest of Whittier. It is famous for its sheer granite walls, hanging valley glaciers, and massive waterfalls that cascade thousands of feet into the sea.
Navigation & Safety
- Katabatic Winds: Cold, dense air masses frequently roll off the massive icefield at the head of the bay, cascading down the Blackstone and Beloit glaciers. These katabatic winds can reach severe storm forces with little warning, even during warm, sunny weather. Always verify anchor set and monitor holding closely.
- Glacial Calving: Keep a safe distance of at least 1/2 mile (1,000 yards) from the active calving faces of Blackstone and Beloit glaciers. The resulting waves can sw swamp small boats and push icebergs violently.
- Anchorages: Safe anchorages inside the bay are limited due to extreme water depths. The primary wilderness anchorage is located near the eastern side of the bay’s head, but it remains exposed to severe katabatic wind flows.
