An Arkansas man is missing after he never returned from a hike at the Buffalo National River last week, officials said.
The search for Clinton “Preston” Smith, 67, entered its third day Monday along the Hemmed-in-Hollow Trail in Newton County, the National Park Service (NPS) said.
Bloodhounds were deployed on Saturday, but rainy conditions in the afternoon temporarily stalled the search.
Officials said no further volunteers are needed at this time.
