Volunteers at Point Vicente Interpretive Center.
The 101 whales were counted during a total of 57 sightings. The breakdown: 26 single whales, 22 pairs, six trios, two groups of four, and one group of five.
Schulman-Janiger said she hardly had time to see for herself, as she was too busy marking down sightings made by volunteers, who were careful not to count the same whales twice.
"I remember seeing these large numbers, in those first five years," the researcher said. "But the volunteers who were there Saturday hadn't seen anything like this. It's something they're going to remember forever."
The Whale of a Day festival, which is free to the public, is now scheduled for April 5.
