Strawberry Spit (also Sanctuary Island) is a small artificial island in the San Francisco Bay's Richardson's Bay embayment of Strawberry Lagoon. It is still referred to as Strawberry Spit, although it no longer is technically a spit.
Historically the spit was a haul out area for harbor seals.[1] A channel was built separating Aramburu Island from the mainland to isolate and therefore protect the seals from human disturbances.[2]
The landscape north and landward of Strawberry Spit is dominated by Ring Mountain, whose slopes are strewn with a multitude of boulders that include minerals such as mica, amphibolite and eclogite.[3]
