I haven't checked the Dolores near Rico, but there is A LOT of flour gold in the Dolores from Gateway to the mouth of the river at the Colorado in Utah northeast of Moab, and northwest of Gateway. Actually, the gold isn't much in the river, it's found in fossil river beds from eons ago. You have to move a lot of dirt, but if you find a good spot, it can be worth it from an "adventure" perspective. The gold is so small it takes a lot to make a gram. There are some GPAA claims southeast of Gateway, but I haven't been there. There are a couple northwest, too, and although I haven't found a decent pay streak yet, there's lots of black sand.
The big problem with the Dolores in this part of the state is access. You have to go to Google earth to find roads, then copy coordinates to your GPS. Googgle Earth uses WGS 84 map datum, so make sure your GPS is set for WGS 34. There are very few places you can drive close enough to the river to gain access. The canyon walls are steep, and the river is remote. If you go the the mouth of the river there are two ways to get there that I'm aware of. One is via I70 from Grand Junction to the Cisco exit, then follow the signs to Moab. There is a bridge across the Colorado a long time before you get to Moab, and just up river is a historical bridge called Dewey Bridge that was burned out by kids playing with matches about 10 years ago. There is a dirt road to the left just after you cross the modern bridge that leads to the Dolores. You have to be careful not to miss the turn off to the river from the main BLM road. I think it is the first left after about a mile. When you get to the river, there is a low water crossing, which right now isn't low. Once on the opposite side, follow the road for about a mile, and you'll see some old placer workings above the river to the left. There is a buried ancient river channel that has been worked, and is still producing gold. Chip away at the gravel, then collect the silt between the cobble, and pan it out, or take it home for processing. Just after you cross the river, there are several places to camp in the ancient lake bed that is now overgrown with Cottonwood, Russian Olive, and willows. The camp sites are clear, and easy to get to. If you want directions from the route through the Colorado National Monument, send me a private message. It's more difficult because it's not marked with signs, but it's a beautiful drive, and you dont' have to drive through the river if you don't want to.
I have to go to work right now, but I'll try to remember to take some photos of the gold I found in 3.5 buckets of dirt from the bench deposit I told you about. I'll let you know when I get it done.
