Last access and rule review: September 18, 2026
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 volcanic field visit for observing young basalt, craters, lava tubes, and active geologic processes from currently open routes.

## Location and material

- State: Hawaii
- Area: Hawaiʻi Volcanoes National Park, Island of Hawaiʻi
- Category: Geology observation
- Collection status: Observation only
- Expected material: Basaltic lava flows, Volcanic glass textures, Crater and rift-zone landforms

## Authorization

National Park Service regulations prohibit possessing or removing lava, Pele’s hair, Pele’s tears, rocks, minerals, dirt, or sand. Scientific collection requires a permit; educational collecting is not allowed.

## Access

Volcanic hazards can close roads, trails, overlooks, and entire districts without notice. Use the park’s live conditions and remain on open roads, trails, boardwalks, and overlooks.

## Tools, limits, and season

- Tools: Camera, binoculars, notebook, and hand lens for non-contact observation only. Do not touch fragile glass, stack rocks, make casts, or leave marked specimens.
- Limits: Take photographs and observations only. No natural geologic material may leave the park.
- Season and current status: Check eruption, air-quality, weather, road, and trail conditions immediately before and during the visit.

## Conditions

- Remove no lava, glass, sand, or soil.
- Stay out of closed areas.
- Remain on required trails and boardwalks.
- Respect culturally significant volcanic landscapes.

## Geology

Kīlauea and Mauna Loa are shield volcanoes built by repeated basaltic eruptions.

Flow texture, weathering, vegetation, and relative position can reveal a sequence, but only official maps should be used to assign an eruption age.

## 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

- Volcanic gases can be hazardous, especially for sensitive visitors.
- Fresh lava surfaces are sharp, unstable, and heat-absorbing.
- Never approach a crack, cliff, plume, or closure barrier.
