Whale watchers off of Dana Point, California were treated to an exhilarating sight this weekend, witnessing a spectacular if unusual phenomenon: the so-called dolphin stampede.
All at once a massive pod of 1,000 dolphins turned the waters around Capt. Dave's Dolphin and Whale Safari boat white, seemingly engaged in one one observer described as a "race", at times topping 25 mph. While the sight of a dolphin stampede is extremely rare, tours by this operator encountered the phenomenon twice this weekend, once on Saturday and once on Sunday.
It is unknown why the dolphins "stampede" or what prompts the bizarre but breathtaking behavior.
