- Riverside Breaks Natural Area Preserve (dnr.wa.gov)
Located above the Okanogan River on a terrace formed 12,000 years ago by receding glaciers, this 36 acre preserve contains examples of two rare native shrub-grassland ecosystems that were once much more extensive along the Okanogan River and northern Columbia River. The preserve also supports a population of Snake River cryptantha, a state-listed sensitive plant species found only in arid shrub-grassland habitats. The Lime Belt wildfire burned through the entire preserve in 2015, removing most of the shrub cover but leaving an intact native grassland.
