Jerry Langford of Lake Forest and his family started their project by digging a trench and sending the sand over to their friends working in the adjacent building area.
"We have an archeology grad on the team this year," Langford said. "So we decided to go with buried treasures."
Langford's daughter, Jacy, said their team had been building sandcastles in the Corona del Mar contest for 10 years.
"Look, he's using a shovel to make a shovel in the sand!" a passerby said as they watched the archeological dig take shape in the sand, complete with skulls, a shovel and a treasure chest.
Nearby, two girls pronounced a sand dragon as their second-favorite of all the contest entries.
"What will it take to make it your first?" said creator J.D. Barnes of Palm Springs. The girls told him a face before running off; Barnes began shaping eyes with the side of a trowel.
Other creations included a ship, a Thomas the Tank-type train and an octopus. Nearby, non-contestants made their own sandcastle creations, apparently inspired by the stunning works of the experts.
