A family's nighttime anchorage in Alaska's Glacier Bay took a dramatic turn when their sailboat was struck and sank. The incident occurred while the parents were asleep, but their 23-year-old child was awake and alerted them to the situation. The family had to swim to shore in the dark.

The mother, Tania Lewis, is a wildlife biologist at Glacier Bay National Park, although she does not work with marine wildlife. She and her family are familiar with the area, often traveling by boat. Further details about the incident, including the events that followed, are available from the source.
