The Reefs of Howe Sound
Howe Sound is a high run off body of ocean water located along the edge of Vancouver, B.C.
The Sound is home to an abundance of marine life and was formed by a two kilometer thick glacier, which started to retreat approximately 10,000 years ago, leaving behind a glacial till rich in silica.
This created a perfect environment for glass sponge.
The reefs in the Howe Sound ARE THE ONLY KNOWN LIVING glass sponge reefs in the world that are reachable by divers.
