LONG TIME, NO SEA: The Sea Explorer...

LONG TIME, NO SEA: The Sea Explorer will be berthed at Dana Point, but once it could have docked in Yorba Linda. . . . About 20 million years ago, the ocean shore repeatedly advanced and receded over Orange County, leaving behind traces of sea life. . . . Whale bones and scallop shells the size of dinner plates have been found in the Saddleback Valley. In the 1920s, vast concentrations of marine shells in Laguna Hills were mined and sold as soil additive. . . . Sea plants formed the white sediments and oil deposits found as far inland as the Puente Hills near Brea.
