I'm strictly a detector operator, so when a friend asked me about the ins and outs of dry washing on public lands, I was at a loss. I told him that I would ask the knowledgeable folks here on the forum. Specifically, is dry washing considered casual use of the land, just as metal detecting and panning are? Is a mining claim and/or notice of intent or plan of operation required for motorized dry washers? Thanks in advance for your insights!
