The Rim Fire was a massive wildfire that started in a remote canyon in Stanislaus National Forest, in California. This portion of the central Sierra Nevada spans Tuolumne and Mariposa counties. The fire started on August 17, 2013, during the 2013 California wildfire season, and grew to be (at the time) the second-largest wildfire in California's recorded history and the largest recorded in the Sierra Nevada, having burned 257,314 acres (402.053 sq mi; 1,041.31 km2). As of 2022, the Rim Fire was California's 11th-largest modern wildfire. The Rim Fire was fully contained on Thursday, October 24, 2013, after a nine-week suppression effort by firefighters.
