Historical Overview

Sebastián Rodríguez Cermeño's Manila galleon San Agustín wrecked in Drakes Bay in 1595 and is treated by the National Park Service as the first recorded shipwreck in California history. Accounts describe the vessel losing anchor in a storm, driving ashore, and leaving cargo behind while survivors escaped south in a smaller craft. Archaeological work in the Drakes Bay district has tied sixteenth-century contact materials to this event and to the wider early-contact landscape at tamál-húye. For treasure hunters the story is compelling, but in practice this is a protected archaeological landscape rather than an open recovery site.

Field Search & Recovery Tips

Treat the whole bay-beach-estero complex as the relevant search area rather than a single point. Focus on museum collections, NPS interpretation, and storm-exposure geomorphology; do not disturb beach deposits, dunes, or submerged material. If you are reconstructing the wreck vicinity, compare historical shoreline change with present-day sand movement and exposure.

Field Action Checklist

1
Use the source link, public overlooks, museum records, or agency pages; do not disturb the ground or wreck site.
2
Record photos, bearings, and public interpretation notes instead of collecting objects.
3
Contact the managing agency before any research that goes beyond viewing or documentation.
4
Check tides, swell, marine protected areas, and vessel traffic before any shoreline or water visit.
