The description states:
POINT LOBOS, a dramatic meeting of land and sea. Trails and road give access to spectacular views. On Highway 1, just south of Carmel.
–While it may seem to be a trick of photography, the color of the ocean water at Point Lobos is indeed this exceptional shade of blue.
This image likely dates from the 1970s.
