Researched extensively since the early 1970's, this book covers the author's “backyard”. In it's sixth edition, this guide covers the I-5 Corridor from Portland to Cow Creek, south of Canyonville. There is an emphasis of where to go to pan without a claim. Nine maps give locations and directions of placer mining areas, and some lode mines. Mile by mile tours through mining areas with specific observations, and first hand mining experience. Basic instructions on panning, sluicing, and prospecting.
