I used my Bazooka Gold Trap in Kaufman Creek. I dug one hole along the bank down to a blue clay layer. I only ran about 6 quarter full buckets of unclassified material. I got fine gold and a bunch of black sand. It was a fair rate of recovery for only a short time in an area where I have never prospected and had very little knowledge. It is a beautiful place too with some good dispersed camping.
