- This 240-acre site preserves one of the last remaining examples of the vast native arid grassland that once covered much of the eastern Columbia Basin in Washington. A population of Piper’s daisy-a state-listed sensitive plant species that grows only in the Columbia Basin-occurs within the preserve. This site was designated a National Natural Landmark in 2011, in recognition of its nation-wide significance to natural area protection.
- Racehorse Creek (wa100.dnr.wa.gov)
Racehorse Creek, a small waterway near Deming, Washington, is a must-see destination for fossil aficionados. The area is known for its fossil beds—50 million-year-old leaf fossils, including sycamore and swamp cypress, await dedicated collectors. In addition to abundant fossils, the creek boasts the impressive Racehorse Falls, a 169-foot-tall multi-stage waterfall that’s a short 0.6 mile hike to reach.
