L334 Back on the Rocks

I was delighted to see an enormous female elephant seal show up on the boat ramp this afternoon. Turns out she’s well known to the rocks. Born in 2023 in the Año Nuevo State Park, California, she has made regular appearances here over the last few years! Most recently in May of this year by Christine, also in October 2025 and 2024 with Kendra, first mentioned in April of that year as a skittish, young female.

How things have changed! She is around 3-4 years old now, and significantly larger. As soon as the Outlook outage is sorted, I’ll send a report to the researchers at Año Nuevo to let them know she’s come back.

Facility Notes

  • tested new fire pump setup early morning; in the end didn’t manage to get much up to the cistern before the tide came in a tad too close for comfort
  • collected driftwood, laid out to rinse in the rain
  • tidied up indoors

Weather

Sunny, intermittent clouds. Mostly North-Northeasterlies from 2-13 knots during the morning, picking up to 26 knots by the evening. Temperatures from 11-14 degrees.
