Point Sal is a 77-acre promontory on the coast of northern Santa Barbara County near the north end of Vandenberg Air Force Base. It is a fragile area, with sandy soil and a unique blend of wildlife. Sea lions, mussels, and deer can be found just yards from one another. Threatened or endangered species such as the peregrine falcon, California brown pelican, California least tern, southern sea otter, and California gray whale are regulars at Point Sal. The area is also a unique meeting point and transition zone for tidepool life and plant life common to the northern and southern coasts of California. There is abundant evidence of Native American occupation as recently as 250 years ago and as far back as 4,800 years ago. Rock rings where homes once stood, grinding stones, and other Native American artifacts are easily visible. Point Sal is managed by BLM as an Area of Critical Environmental Concern.
