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.

Malachite is unmistakably green — from bright emerald crusts to dark banded masses — with a silky-to-dull luster and a pale green streak. It is soft (3.5–4, scratches with a knife easily) and fizzes gently in vinegar. Banded, rounded (botryoidal) surfaces are classic. Blue azurite alongside it is a bonus find from the same chemistry.

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.
