With less than two weeks left in his presidency, President Joe Biden designated two new national monuments in the West. Biden signed proclamations Tuesday creating the Chuckwalla National Monument and the Sáttítla Highlands National Monument, both in California, covering 848,000 acres of land.

Tribal communities in Northern California’s mountainous interior are celebrating the recent designation of Sáttítla Highlands National Monument after decades of advocacy work to increase land protections in the area.

Biden has federally protected 1,053,125 square miles of land and ocean in his term — an area nearly four times the size of Texas.
