CCRMC frequently arrange field trips to rock collection areas and mines - or participate in field trips arranged by the CFMS or AFMS. Some are day trips, other are overnighters, either with a nearby hotel/motel, or where a camper or tent is required.


Hunting for Orbicular Rhyolite at Ord Mountain

When:Saturday, December 2 @ 8 am (changed from November 18)

Meeting Point: Tronyan Coffee Roasters, 13528 Nomwaket Rd, Apple Valley, CA 92307

From the meeting point, we will be driving about 15-20 miles east of Apple Valley before driving on
gravel roads of varying quality for approximately 9 miles to reach the collecting site near the base of Ord Mountain. The trip should not require any extensive hiking or off-road driving but a high-clearance or 4-wheel drive vehicle would be preferred.

The collecting material is spread throughout the area and better quality specimens can be found further from the road where we will park our vehicles.

The abandoned Grand View Gold Mine is near the collecting site and small fragments of gold have been found on occasion. Orbicular rhyolite is quite plentiful at this location and is best used for larger work such as bookends, spheres, etc. Higher quality material can be made into cabochons.

Suggested Equipment: Rock Hammer, Eye Protection, plus the obvious (water, snacks, hat, etc.)

Please RSVP via email to or 310-980-4165 and also feel free to contact me for
questions, etc.
