President Joe Biden has expanded two culturally significant California landscapes: the San Gabriel Mountains National Monument in Southern California and Berryessa Snow Mountain National Monument in Northern California.

President Joe Biden on Thursday will formally sign a proclamation expanding two national monuments in California and protecting nearly 120,000 acres of land, according to the White House.

C alifornia has 19 national monuments, the most of any state in the U.S. And more than half of its monuments were proclaimed more than 90 years after the establishment of the Antiquities Act in 1906.
