Humpback whales in Sacramento

Two humpback whales, a mother and her calf, have found themselves about 90 miles from the Pacific Ocean. They swam through the Golden Gate and then upstream through the Sacramento-San Joaquin Delta, where they are now apparently hanging out.

The mother was injured by a boat propeller and has a 2-foot long 6-inch wide gash near her dorsal fin. Marine biologists are hoping to lure the wayward animals toward the Pacific with recordings of whale songs where they can find food and the salty water can heal the mother's injury.
