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.

The president also designated a second monument in Northern California. Biden however, did not include a proposed third monument, which was supported by tribes in Imperial County.
