Coastal visitors were reminded to exercise caution when exploring exposed tidepools. On Tuesday, a woman in a tidal pool at Boiler Bay fell and injured her ankle. The 45-year-old had to be airlifted from the tide pool by the U.S. Coast Guard to a nearby parking lot because of the slick and uneven terrain of the pool.
