allcreatures:snuh:findout:”Each year in July, hundreds of beluga whales congregate to mate and give birth in the mouth of the Cunningham River where warm, fresh water blends with the cold, salty arctic sea. During high tide they swim upstream with their backs barely covered by the shallow water, their stomachs rubbing the small rocks of the riverbed”. Norbert Rosing, photographer
