The Cowichan Head bluffs can be accessed by walking along the beach at low tide from the nearby Island View Regional Park to the north. The sand and clay bluffs have been eroded away, leaving a nearly-shear cliff that clearly shows the many different geological layers of the last ~100,000 years.

One of the layers, a soft clay layer called the Dashwood Drift, dates from between 80,000 and 65,000 years ago and contains body fossils of bivalve shellfish. This layer is at beach level at the coordinates, and is higher up on the bluffs to the north. Pieces of this layer are frequently eroding away and falling to the beach, providing easy access to the fossils. The chunks of dark-grey clay yield many different types of bivalve fossils. Fossils found on the beach can be legally collected and kept by amateurs, though the fossils officially remain the property of the Province of British Columbia.

Another layer up higher on the bluffs, the Quadra Formation, dates from 29,000 to 23,000 years ago. Mammoths roamed this region during that time, and some mammoth bones have been found on the beach in the past after they've fallen down from this layer. Such finds are very rare, though, and any mammoth remains cannot be legally kept by amateur finders and must be turned over to the Province.
