[QUOTE="tvanwho, post: 188707, member: 5785"] I will be out at the gemstone creek next weekend, dunno if can get my big banker in there by myself since its down a short but VERY steep dirt hill, at the bottom of which I need a machete to cut thru the thick brush, then have to get my stuff across thigh deep water with sandy bottom 15 feet upstream to the gravel bar.The creek comes up 1-2 feet in even a light rain. Will take some photos to post. May have to just take my micro banker with WX10 pump for now, will run the sluice as flat as I can, and put a tub under the discharge so I can catch the pebbles for gemstone examination later. Will defintely be on a sharp lookout for pretty stones and save them out. I did install some 1/4 inch tall raised sloped expanded under the riffles, had it welded to the riffles. The micro banker sluice is only 2 feet x 7 inches. It did catch a large blue sapphire crystal a year ago in the perf metal grizzly area.It has 1/2 inch square holes.Will be looking for diamonds too and have my UV flashlight for that.Some diamonds glow blue under a blacklight. Wonder if it matters what wavelength of UV to use? Got any advice on that Wal? And should I examine the pebbles at night on a paper towel/cookie sheet or what? Will sapphires or other gemstones glow in the UV light? -Tom V. [/QUOTE]
