What’s in a Name?

Originally called Black Mountain by government soldiers in 1875, this Moffat County peak was renamed Shield Mountain by local residents in 1931 when a large landslide on the south side of the mountain settled into a shape resembling a shield. We like to think that Shield Mountain just sounded like a cooler name so kudos to the locals.
