Located in east central California just north of Death Valley, and on the western edge of the Great Basin, the White Mountains rise to a respectable altitude of

The White-Inyo Range extends from Montgomery Pass south-southeastward to Malpais Mesa in the Owens Lake area, a distance of 110 miles. The mountains here rise from valleys on the east and west. The separation point between White and Inyo mountains is placed at the Westgard Pass road (Hwy 168) a division with no geographic importance. This range reaches its greatest width (22 miles) east of Bishop. The rise from the Owens Valley floor at 4,000' to elevations of more than 14,000' is abrupt, occuring within a 12 mile line. These ranges have more ties with plants and animals to the east in the Great Basin, than their close neighbor the Sierra Nevada, only 10 miles westward.
Weather here is cold and dry. The average max.-min. temperatures range from about 70°F (21°C) to 37°F (3°C) at the base, and from 36°F (2°C) to -26° (-32°C) in the alpine zone. Precipitation averages 4 in (10 cm) at its base to 20 in (50 cm) mostly as snow, along the crest. Due to the varied topography, precipitation can and does differ greatly in localized areas. Winds blowing along the crest can blow most of the snow from some areas, leaving little for trees like the bristlecone at the treeline (11,200 ft.). Thunder and lightning storms occur frequently in the high country. Winds are strong at the crest, both summer and winter.
The dry climate and high altitude make this region a rare environment. The rapid changes in elevation create abrupt habitat and species changes. The soil quality is poor, and at its poorest in the alpine zone. This factor combined with a short growing season, results in sparse and delicate flora. Recovery from disturbance is slow, said to take more than 100 years! This is truly an area that one must be careful in preserving.
Driving along Hwy 395, and looking up at the White-Inyo range, it's appearance is somewhat barren and inhospitable, but once there we are gifted with sights and beauty unimagined from below. In August the wildflowers are abundant, the night sky clear and breathtaking; and it is so quiet here you can actually hear the wingbeats of small birds! The bristlecones are reason enough to travel here, and with the abundant flura, wildlife, and vistas, we are compelled to return.
The geologic makeup of the White Mountains is of quartzitic sandstone and granite bedrock. A large part of the soils on these slopes have been swept away by the extreme conditions. Also present are extensive outcrops of dolomite (limestone) a very ancient rock first laid down under water 500 million years ago, then slowly uplifted through time. Numerous fossils of this period can be found here. It has been speculated that one could have walked chest deep across the early Paleozoic sea located in the region at that time. The dolomite is low in nutrients but of a higher moisture content than the surrounding sandstone. Because these soil types inhibit the growth of other plants, they provide a competition-free arena for the slow-growing bristlecone pines.
The spectacular panoramic views of the Sierra Nevada along with the Ancient Bristlecone Pine Forest are the principal attractions for tourists. Due to the lack of water (you must bring your own), camping and other recreational activities are light.

Because the forest is such a special place, everything possible must done to preserve its fragile and irreplaceable environment. This area has been classified as a Botanical Area and is set aside for scientific research and public enjoyment. The following are rules established by the U.S. Forest Service:
