A woman from Minnesota was reportedly among those injured when a gray whale smashed into a tourist boat off the Mexican coast this week, killing one person.

WindomNews.com reports that Kim Armstrong, of Windom in Cottonwood County, was vacationing with her sisters Caroline and Sarah in Cabo San Lucas when the surfacing whale landed on the inflatable sightseeing vessel.

"She is in San Diego now," her husband, Todd Armstrong, told the newspaper. "She is having surgery in her neck area," explaining that she's been told she has fractured two of her vertebrae.

Armstong was reportedly sitting next to the woman who was killed in the incident, whom has been identified by the National Post as Jennifer Karren, a 35-year-old from Calgary, Canada.

The National Post said the boat was carrying nine tourists on a snorkeling tour when the whale breached at around 11 a.m., hitting the side of the boat.

"The captain had to make a movement to avoid a whale that surfaced just in front of the boat," a statement from tour company Cabo Adventures said, according to the Guardian. "The whale hit one side of the boat, leaving two people injured and another passenger hurt who, unfortunately, later died in hospital."

The Guardian notes that whale watching is one of Cabo's major attractions, and says the incident happened a day after Mexican authorities had announced there was a particularly high number of gray whales gathered in the area.

National Geographic says gray whales typically grow to the size of between 40 and 50 feet, and can weigh 30-40 tons.
