He was transported to a local hospital where he was reunited with his family.

An elderly man who had vanished while hiking in Northern California was found alive Tuesday night, authorities said.

Robert Bennett, 76, was reported missing on Monday after he failed to return from a hike in a Marin County nature preserve. The Marin County Sheriff’s Office had said Bennett was last seen that afternoon walking toward a trailhead that leads to Big Rock Ridge, which borders the cities of Novato and San Rafael.

Search and rescue teams scoured the trails in the area all day Tuesday.

“We anticipate working through the night trying to find Robert,” the Marin County Sheriff’s Office said in a post on its official Twitter page.

Police dogs eventually found Bennett that night and directed rescuers to his location. The Marin County Sheriff’s Office tweeted that emergency crews were “working on extracting him,” without providing further details on the matter.

Bennett was later transported to a local hospital where he was reunited with his family. The Marin County Sheriff’s Office said his condition is unknown at this time.
