How to Identify Silver
Native silver rarely looks silver in the field — it tarnishes dark gray to black. The tells are its wire and branching (dendritic) growth habits, serious heft, and malleability: a knife point digs a bright metallic groove instead of flaking the surface. On mine dumps, dark heavy pieces that cut rather than crumble deserve a second look.

The basics: a rock hammer, safety glasses, gloves, a bucket or padded bag for specimens, and a GPS app with the coordinates from this page. Add a spray bottle — wetting a stone makes color and banding far easier to judge in the field.
