This small nature park is a delightful springtime stop, and a cool oasis in the summer. A narrow footpath lined with trillium, bleeding-heart, and other wildflowers descends into a ravine with fern-covered basalt outcrops, then winds up the opposite slope. Dense willows at the bottom are buzzing with Rufous Hummingbird by April. Orange-crowned Warbler and other riparian species can be expected later in the nesting season. Nearby Dalton Lake hosts waterfowl, plus woodpeckers and songbirds in the surrounding woods. Follow a paved trail from the Columbia Humane Society, and hike dirt path leading to a cliff overlook.
