Marin County Search and Rescue crews were trying to track down two missing men Tuesday in separate cases, according to the Marin County Sheriff's Office.

Klingenmaier is 5 feet, 7 inches tall and weighs about 172 pounds, with brown hair and hazel eyes. He went hiking to an unknown destination, the sheriff's office said.
The second search was for 73-year-old John Hollabaugh, who was last seen on Alta Avenue in Lagunitas, just outside of Samuel P. Taylor State Park.
Hollabaugh is 6 feet tall and weighs 180 pounds, with gray hair and blue eyes, sheriff's officials said. Description of his clothing was not available.
He left an address on Alta Avenue on Saturday and has been missing since.
