Hanson Island Orca Rubbing Beach · 360° Habitat Camp
What to look for
- Smooth marble-pebble spa shelf — Cultural pebble-rubbing substrate. Centre the sorted sublittoral cobble shelf used exclusively by Northern Residents
- Chinook salmon tidal narrows — Oncorhynchus tshawytscha echolocation corridor. Locate the tidal current race where matriarchs echolocate Chinook salmon
- Coastal redcedar acoustic cove — Thuja plicata & OrcaLab hydrophone shore. Scan the forested island shoreline housing non-invasive hydrophone arrays

Ask together: Does your family have a special song, joke, or tradition that nobody else's family knows—just like an orca pod?
