## Geology

Geodes form when mineral-bearing fluids deposit silica or calcite inside cavities in sedimentary rock.

A rounded nodule may be solid; do not promise a hollow or crystal-lined interior.

## Field plan

1. Open the current official source and check alerts before leaving home.
2. Confirm the property boundary, parking location, and activity rules on arrival.
3. Begin with observation or surface searching and make the smallest possible disturbance.
4. Photograph context before handling any material that the current rules allow you to keep.
5. Pack out every item you brought and leave protected or uncertain material in place.

## Safety

- Flying rock requires goggles.
- Use gloves and stable footing.
- Open geodes only by a method and in an area approved by the operator.
