Hello all!
This is sort of a continuation of an earlier post, but it can stand on its own.
http://www.treasurenet.com/forums/p...t-gold-panning-trip-gravel-bar-questions.html
So, I went back to the same spot as before, but I moved up stream, to right in front of this bridge (see first photo in previous post). There are a couple of large rock sticking up in front of the tunnel, and thought that would be a good place to dig. However, it became very apparent that getting the material out without it washing off the shovel is going to be a challenge. Another fella came by, and he made the same comment on a spot further down stream; good spots behind large rocks (and right near some bedrock), but the material washes off his shovel. I was able to get a small pan right in behind the rock, and get some material in the pan, using my hands. After panning it out, I might have found one spec of color, but I would not bet on it (I put it in a bottle anyways to look at later).
Here is my question: Are there any tip/trick/suggestions for getting material from behind a rock in the middle of a fast moving stream ?? I know the most obvious answer is to use a dredge, but being on federal lands, they are prohibited (well, the rules says nothing mechanized or motorized; I wonder if a gravity dredge would be allowed??
.) Could one try submerging a sluice box? (I googled that, but did not see much on it). Is there a ways to capture that material, and then pan it on the shore? I figured someone here has dealt with this problem before . . . I know...they probably used a dredge! 
Thanks for any feedback!
