Old Woman Mountains Wilderness

This Wilderness area consists of bajadas; extensive flat aprons of alluvium; and the massive, fault-lifted Old Woman Mountains that extend some 35 miles north-south and up to 28 miles in an east-west direction. The mountains take their name from a granite monolith resembling the figure of an old woman, known as the Old Woman Statue (5,000 feet high). The elevations within the Wilderness extend from 800 feet in the drainage bottoms to over 5,300 feet at the top Old Woman Peak. The Old Woman Mountains were the discovery site of the Old Woman Meteorite, which was discovered in 1975 and is the largest meteorite found in California and the second largest in the United States.

The line is the average temperature at Iron Mtn, 22 miles from the center point at 922 feet, station USC00044297 in the NOAA monthly climate normals for 1991 to 2020. The station sits about 3,200 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
