The area south of Topock is rugged and may hold many stories. It would be nice to go there on a cool winter day, and metal dedect in the streems. Gold will travel down washes a ways and maybe you coul dtrace it back up to its source. A word of caution, the area south of Topock was designated as the Chemehuevi Mountain Wilderness back in 1994, so please stay out of there on mechinized vehicles. But that can't stop you from looking eh? Maybe you will be lucky and if the gold is in clay, heck, just dig it out and don't say anything. I like that
Gold in a clay and in nugget form would indicate to me a placer deposit of some kind. So rather than looking for quartz seams it may be best to look out for old sedementtry rock. Maybe on a terrace or if we could only go back in time when the colorado was at a higher level, see where aincent river beds were. Two days burrowride, hmmm. Not sure how far a laden borrow can travel in a day, but maybe 15 miles on a good day? so 30 to 40 miles of Topoch. That would place it somewhere in the Mohave Mountains in Arizona. North of Lake Havasu area. It is interesting because there are old mines in that area, while according to topo maps on the wast side in the wilderness, there are no mines. Still isn't it great to be able to dream of finding that lost treasure?
