Page purpose: Original LithoMap trip-planning reference for a protected or rules-limited geology destination where this guide authorizes no removal.

## Direct answer

A no-collection visit to fragile Niobrara Chalk spires and marine-fossil-bearing strata, viewed from marked trails or reserved guided access.

## Location and material

- State: Kansas
- Area: Little Jerusalem Badlands State Park, Logan County
- Category: Geology observation
- Collection status: Observation only
- Expected material: Niobrara Chalk, Cretaceous marine fossils in place, Badlands landforms

## Authorization

Kansas Department of Wildlife and Parks expressly prohibits fossil hunting and collection of rocks, plants, or any other natural material at the park—even loose objects on the ground.

## Access

A state-park vehicle permit is required. The park is day-use only; off-trail access is limited to reserved guided tours.

## Tools, limits, and season

- Tools: Camera, binoculars, and notebook only. Do not touch fossils, climb formations, leave trails, or use a collecting tool.
- Limits: Observation and photography only. Take nothing from the park.
- Season and current status: Open sunrise to sunset year-round, subject to weather, road, fire, and tour conditions.

## Conditions

- Stay on marked trails unless on an official guided tour.
- Collect nothing.
- Do not climb or touch fragile chalk formations.
- Carry out all waste.

## Geology

The Niobrara Chalk accumulated in the Western Interior Seaway roughly 85 million years ago.

Differential erosion sculpts the soft chalk into steep spires, making off-trail traffic especially damaging.

## 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

- Chalk surfaces and slopes can be unstable.
- The open landscape offers little shelter from heat, wind, lightning, or winter weather.
- Carry water; none is promised on the trail.
