The Old Woman Mountains are located south of the town of Essex, California, and north of Danby Dry Lake. The range reaches an elevation of at the northeastern end (Mercury Mountain), and lies in San Bernardino County in the Mojave Desert.
The mountain range is approximately wide east to west at the widest point, and in length from north to south. The mountains receive very little precipitation, with just 4-10 inches of rain falling in a normal year. The Old Woman Statue, a prominent rock formation, is found on the eastern side of the range about two miles (3 km) south of Paramount Spring. The Old Woman Mountains Wilderness area is also part of the range.
The lower elevations of the range are dominated by Creosote bush scrub, with juniper-pinyon woodland found in the higher elevations. The dry washes are characterized by catclaw acacia, cheesebush, desert lavender, little-leaf ratany, and desert almond.
Animals found in the mountains include: bighorn sheep, mule deer, bobcat, coug (from [www.wikipedia.org](http://www.wikipedia.org/wiki/Old_Woman_Mountains).
