On the upland above Hillers Creek, oak and hickory trees grow scattered on the grass and sedge-covered area we call “The Savanna.” It’s a transition between prairie and woods. Historically, Missouri was about a third savanna kept semi-open by the fires of Native Americans. Along the edge of The Savanna, fragile moss and lichen cover the rocky bluff tops. Sandstone just under the surface creates a thin, acid soil that supports flowers such as birds-foot violet and wood betony that bloom in spring. The Valley Overlook is a special platform that protects the plants on the bluff edge but gives you a sweeping view across the Ozark-like landscape below. A bench makes it a pleasant place to pause.
