A rescue operation was conducted on Monday to evacuate 13 hikers trapped in a wildfire zone near the Tahoe National Forest in Placer County, California. The Placer County Sheriff's Office initiated the search after discovering the hikers' vehicles in the area where the Royal Fire ignited around 4 p.m. on Sunday.

A helicopter crew located the group around 7:20 a.m. on Monday. "Search and rescue crews will join them to hike out," the sheriff's office said in a statement.

Elise Sovier, spokesperson for the Placer County Sheriff's Office, reported that the hikers, aged between 16 and 20, set out together on Sunday before the fire started. Despite their familiarity with the trail, the fire blocked their path, forcing them to seek an alternative route.

No injuries were reported among the hikers. The Royal Fire had burned 169 acres as of Monday and was not contained, according to Cal Fire.
