Sedimentary
2,753 ft (839 m)

Sandstone and sandy shale, brown or yellowish-brown to white. Horizontal layers form a mesa-like plateau. Rocks of similar age south of the Arkansas River Basin, in the Ouachita Mountains, are much more deformed due to collision of a land mass with Laurentia in late Paleozoic time. Signal Hill is the highest point on the mountain. Ross Hollow Overlook provides distant views and also a close look at cliffs of bedrock.

Soil Series: Mountainburg gravelly fine sandy loam. Moderately deep, well drained, gently sloping, strongly leached, acidic soil developed on sandstone under mixed pines and hardwoods and understory of tall grasses. Xeric, stunted forest.
