The Arkansas Group claims have flour gold; however, the BLM limits your activity there to non-motorized equipment or re-circulating, battery operated units. The Arkansas that runs through the claims is also popular with rafters and fly fishing folks. The claims are also adjacent to private property and with all the public activity, many property owners are touchy about trespassing.You can get good local maps at the tourist bureau in Buena Vista. Here is the BLM website about these claims:
