On a mid-December sunny day I hiked from Valleyview Arena across Highland Drive, then up into the silt cliffs benchlands between Owl Road and Highland Road. The benchland area is sagebrush grasslands cut by deep gullies and pocked with sinkholes.   I followed both double tracks and single tracks around the gullies. Silt cliffs line the sides of each of the larger gullies in this area. I followed a series of tracks on dirt, some snow, and some mud, then returned to the Arena retracing my route. This is a good shoulder-season hike, especially since you will be unlikely to see anyone else.
