Flatside Wilderness

In the extreme eastern Ouachita Mountains is a Wilderness that takes its name from Flatside Pinnacle, a 1,550-foot rock outcropping just outside the northeast boundary. In 2019, the Wilderness was expanded and the added acres named the Bethune Woods-Flatside Wilderness addition in honor of former Representative Ed Bethune. Dominating the skyline are White Oak Mountain, the highest point in the Wilderness at 1,650 feet, and Forked Mountain, at 1,350 feet. From overlooks on the eastern and western sides, the forest below looks like an unbroken canopy of pines and hardwoods. Several small creeks flow through the area.
