A natural log fireplace mantel is both bold and elegant. These majestic natural wood mantels show off the complex textures, knots, and twist of a real tree. While in nature these trees grow in many shapes but rarely twist. As a result, finding a gnarly twisted gem is like finding a needle in a straw stack. Also, because of the twist and gnarl, the shelf is not always a consistent depth and thickness. At the same time, the inconsistent gnarly and twist is what makes logs the perfect rustic log mantel.
