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 types of native shrub-grassland ecosystems.  These ecosystem types were once much more extensive along the Okanogan River and northern Columbia River, but are now restricted to only a few small locations.  The site also supports a population of Snake River cryptantha, a state Sensitive plant species found only in arid shrub-grassland habitats.  (Okanogan County)
