Page purpose: Original LithoMap trip-planning reference for an explicitly authorized rock, mineral, or non-dinosaur fossil collecting destination.

## Direct answer

A scheduled citizen-science dig where registered participants excavate with state paleontologists and finds are handled under program rules rather than personal collecting rights.

## Location and material

- State: North Dakota
- Area: Rotating NDGS field sites
- Category: Fossil collecting
- Collection status: Program or paid access
- Expected material: Scientifically documented fossils, Site-dependent fossil material

## Authorization

The North Dakota Geological Survey runs public fossil digs at announced sites and publishes registration, age, safety, and event requirements.

## Access

Locations rotate and are disclosed through the current program. Join the notification list and use only the route and arrival instructions sent for a registered dig.

## Tools, limits, and season

- Tools: Use tools, stabilizers, and excavation methods supplied or approved by NDGS staff. Do not independently prospect around the dig.
- Limits: Fossils and their data are scientific resources; assume finds remain with the program unless staff expressly say otherwise. Participation is not a permit for later collection.
- Season and current status: Events are normally scheduled in summer and fill quickly; use the current waitlist and event page.

## Conditions

- Register before attending.
- Meet the event age rule.
- Remain with the assigned crew.
- Turn every find over for documentation.

## Geology

Each rotating site represents a particular North Dakota rock unit and ancient environment, so the official briefing—not a generic locality list—defines what participants may encounter.

Position, orientation, association, and sediment can be as important as the fossil itself.

## 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

- Expect sun, heat, wind, rough ground, and repetitive hand work.
- Bring every item on the program packing list.
- Stop excavation immediately if staff identify an unstable or delicate find.
