Norwood pottery, the earliest known pottery in North America, helped archaeologists identify the park's oldest site, placing the earliest human activity 2,500 to 3,500 years before the Spanish arrived. These Native Americans hunted, fished, collected clams and oysters, and lived in relatively permanent settlements due to the abundant resources of the coast and forests. In the mid-1800s and late 1900s, fishermen established seineyards at Bald Point. These usually primitive campsites included racks to hang, dry and repair nets. Evidence of the 19th to 20th century turpentine industry is seen on larger pine trees cut with `cat face' scars.
