Daisy Cave, a rockshelter site on San Miguel Island — the westernmost of the Channel Islands, adjacent to the western end of Santarosae — has produced one of the most informative assemblages of early Holocene material from the California coast.

The site yielded evidence of occupation from approximately 11,600 to 8,000 calendar years ago, with a remarkably rich organic preservation.

Shell middens document intensive shellfish harvesting.

Bone tools, fishhooks made from shell, and cordage made from sea grass are among the preserved organic materials.

The fishhooks from Daisy Cave are among the oldest in the New World — evidence that early Channel Islands people were engaged not just in shellfish gathering but in active fishing.

The cordage documents sophisticated fiber technology.
