Natural riffles?

[oregonmp03]

I was up running around this weekend and was checking out a river that I know has gold but that I've never mined myself before. Would the rock formations in this picture act as a natural riffle system at a higher water level? I'm thinking crevicing this area might produce some good results. Thoughts?? My dredging season is over so I'm looking something to keep me going

Absolutely, natural sluices are the best! Dig the low pressure zones and destroy any cracks.

Thanks, I guess i know what I'm doing this weekend

As has been indicated already, yes the natural riffles always demand investigation. If someone would haul a 4" Keene Dredge down a 3000' vertical drop, then take it up river on a poor trail, then take it off trail up a rough creek to suction the dickens out of a creek 'chute' the bottom of which looks like a large sluice box well then, yes natural riffles should be investigated. I would have loved to have seen the site in operation as they should have done well.

Best of success to your investigation.......................63bkpkr

Hello Oregon,

Well, thing is I would KILL to prospect a spot like that. Are you kidding. Bedrock, known gold, natural riffles?! I know others, even guys in the West, are simply drooling at your photo. I am going through Oregon soon and would like to help you out. I will prospect tilted at 90 deg. so the picture is fine as is.

I suggest you spend more time in Florida, or a million other places with NOTHING like that. Get calibrated.

Best regards Oregon, Thurman

How about some like this

 

[Goldwasher]

And there are some deep cracks to be discovered.... notice the orange tint from the damned smoke

 

[Aufisher]

Better get to the bottom of that one GW!

 

[Goldwasher]

Already at bottom there it's the twelve feet to the left and 300 pound boulder that I'm really after

 

[Goldwasher]

Aufisher it's about 150 ft upstream of where you and Hangtowndiggins ran the bazooka that one day...closer to the veins and old digs!

 

[Aufisher]

Oh sweet mother lode!!!

I'm going up at least one day this weekend and see what I can get. I'll post it up when I finish and your more than welcome to tag along if your over in my area this fall although hunting season takes front seat in 2 weeks until mid November.

Don't forget look at how a riffle affects things for a bit downstream...keep in mind it creates a low pressure zone fore several to dozens of feet depending..... look for grips of boulders and gravel deposits....there are hidden cracks with obstacles on top of them that help concentration

Looking closer see where those slabs are slabbing. ...I guarantee you can slab some more and I do belive I see a concentration of black sand. I would hit that visable bedrock and see what else I could strip down. That characteristic that is allowing those blocks to come out should be present under that bank material. Has gold come from that creek locally?

 

[oregonmp03]

I see where you are talking about now with the black sand, the bend in the river upstream has a larger deposit that continues further upstream but I don't have pictures. This is the only real area that the bedrock runs in to natural riffles. The rest of it is turned sideways the wrong way further upstream and downstream.

Bow season is in full swing right now. Give us a clue maybe? I have a guess.....

a guess of where it's at? feel free to PM me viking as I've talked with you before, I don't have a problem with sharing info or even getting together and going out on a weekend mining trip

Keep in mind that there isn't necessarily a "wrong" way for cracks it also depends on the type of bed rock and the area. A parallel crack can actually concentrate material...don't neglect hang ups in "wrong direction" cracks and look where they start and end!
