OBD only stupid question when your a newbie is one not asked. For good practice go to Home Garden outta Quincy go south to feather river,park by the bridge. There is righteous bedrock down stream-flakey easily shattered black shale. Go down about a couple a 100 yards as that shale has been blasted to DEATH but great example of good carrier. Across and down is influx from Nelson Creek on the south side. There used to ba a tunnel below the curve that ran under the river and like a young fool we went in. Back to chest deep water and you can actually hear the river above your head. Leaned on a HUGE support beam and hand went through it like soft mush-exited immediataly. Many claims all over. Copy number,name,camc # and go to recorder to see if legit. Up the road is El(La) ?Portal and feeder creeks have one of the few viable platinium group deposits in mexafornia. BUT in spring,summer fall there are weed grows all over and mobile meth labs show up too. Being alone anywhere unarmed is a fools folly as you never need a gun till ..... it's too late to use it-Join a local yokel club be it gem/mineral/detector or gold as goldnutz are in them all and eases them newbie blues bigtime-John
