U.S. President Joe Biden designated two California sites -- a swathe of desert significant to native tribes and a dormant volcano -- as national monuments on Tuesday, advancing his record of conserving more U.

In an announcement postponed by the Los Angeles wildfires, President Joe Biden on Tuesday designated two sites in California as national monuments that will honor Native American tribes while shielding picturesque mountains and deserts from mining and energy development.

The designations, postponed for a week due to the California wildfires, protect 800,000 acres in the Chuckwalla National Monument and the Sattitla National Monument.
