 Camping on American Girl Mine Rd
 A few miles down Ogilby road you will cross a RR track and then turn right on to American Girl Mine Road.  Traveling down this road you will notice a lot of RV's dry-camped off in the desert.  This is the best "free" place to camp or you can go back down Ogilby road to the Gold Rock Ranch RV park (next to an old gold mine).

 Most of the kyanite ore found in the Cargo Muchacho Mountains of California's southeastern Colorado Desert is grayish- to greenish-blue in color.  The kyanite is found in a quartz, quartzite and quartz-muscovite schist much like the kyanite found at Graves Mountain, GA.  The ore that was mined here varied from about 15 to 35 percent kyanite.  The three deposits, known as the Drifted Snow, the Bluebird, and the Vitrefax, are found near the town of Ogilby (exit 160 on Interstate 8).

Vitrefax Hill mine consists of many cuts and two still usable loading chutes.

Dumortierite
Indian Pass dumortierite probably is as well known as its petrified palm root. It is blue to lavender in color, and occasionally the colors will mix to produce a rather striking bluish purple.  Dumortierite is also known as "Desert Lapis".
Desert-varnish-covered boulders are strewn over the hillsides. 
Jasper - The commonly found colors include gray, brown, yellow, and red.

 The picture above shows one of the interior roads within the collecting area which is now "off limits" to motorized traffic because of the new "Wilderness" designation signed into law by former President Bill Clinton.  Now you have to pack your finds back to the main road parking area.  The elderly and disabled are cut off from collecting in the prime areas of Indian Pass! Camping is allowed along much of the north side of Indian Pass Road as long as you remain within 300 feet of an established road. A fourteen-day limit may be enforced.
