Casual collecting is generally allowed on BLM and National Forest land for personal, non-commercial use — the standard BLM limit is 25 lbs per day plus one specimen. National parks, monuments, and many state parks prohibit collecting, and private land always requires the owner's permission. Check the site report for each location and verify current land status before you dig.

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.
