  the white mountains of california and nevada are a triangular fault block mountain range facing the sierra nevada across the upper owens valley. they extend for approximately  as a greatly elevated plateau about  wide on the south, narrowing to a point at the north, with elevations generally increasing south to north. the range's broad southern end is near the community of big pine, where westgard pass and deep springs valley separate it from the inyo mountains. the narrow northern end is at montgomery pass, where u.s. route 6 crosses. the fish lake valley lies east of the range; the southeast part of the mountains are separated from the silver peak range by block faulting across the furnace creek fault zone, forming a feeder valley to fish lake valley. the range lies within the eastern section of the inyo national forest. ==ecology== ecologically, the white mountains are like the other ranges in the basin and range province; they are dry, but the upper slopes from  hold open subalpine forests of great basin bristlecone pine on permeable dolomite and certain granite substrates and limber pine on less permeable rocky substrates. middle slopes from  have somewhat denser stands of piÃ±on pine and utah juniper. these upper and lower conifer zones are often separated by a zone of mountain-mahogany brush. various subspecies of sagebrush (artemisia tridentata) extend from surrounding valleys to the lower alpine zone  a bristlecone pine in the southern part of the range is the oldest known living tree in the world, at 5063 years old. pine nuts from piÃ±on pine stands were harve
