cleaning off bedrock

My little Fourmile Creek here in Colorado has very little water in it at present. However I do now have a pretty sizable pool to work in. The bedrock is folded and layered gneiss and I am down to it but still have a lot of cleaning to fully expose it. I can suck the pool dry and work the bottom with shovel, pick, winch and hand toss rock, but I'd like to know what some of you might do in my situation to work the bedrock thoroughly. I'll get some current photos together and post them soon.

Re: cleaning off bedrock

Have you considered using Chuck Lassiter's Hydroforce nozzle? Check it out at www.midwestprospector.com

Chuck is a prospecting partner of mine, and I have great faith in his equipment design.

The Hydroforce nozzle looks great. I could use that here in Central Texas.

Re: cleaning off bedrock

faaus,
Thanks for that tip. I'd like to see one of the nozzles at work. Does he have a video? For starters I think I'm going to run my 3" jet with a P180 and a 6.5 hp engine...should get some good suction through a crevassing nozzle.

Nice hole Kurt,

I would suggest draining the hole first, then using say 4 wedges / chisels and a big sledge hammer and a 6' crow bar, I would thoroughly break up all soft rock/ open as many crevices as possible, then re flood the hole and dredge it, not forgetting a good crevice flusher on the dredge or sucker nozzle highbanker combo.

:devil:.
