History Of The Park

Native Americans have inhabited the area of San Diego County for 10,000 years. Evidence of their presence still remains in San Clemente Canyon. They camped around waterholes and streams, hunted game, and gathered wild foods from the area. While harvesting abundant resources, Native Americans were aware of the balance between people and the environment.

In the late 19th century, this area was named Clemente Canyon after a Native American rancher. During the 1970s nature's balance was threatened by plans to place state Route 52 along the canyon floor.

Marian Bear, an active community leader, and environmentalist worked tirelessly to preserve the canyons in their natural state. She was the driving force behind realigning the highway from the canyon floor to the north hillsides. In the 1980s another community campaign resulted in an additional 72 acres in the southeast section for the present total of 467 acres.
