# Dugway Geode Beds: legal collecting field guide

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

## Direct answer

A BLM rockhounding area known for rounded geodes containing quartz varieties in a remote, sparsely serviced desert setting.

## Location and material

- State: Utah
- Area: Tooele County, western Utah
- Category: Rock collecting
- Collection status: Collecting allowed
- Expected material: Quartz geodes, Amethyst, Rose quartz, Chalcedony

## Authorization

BLM lists Dugway Geode Beds as a public rockhounding site. Collection remains subject to current BLM noncommercial-use rules, local restrictions, and the precise authorized area.

## Access

The approach includes a long remote drive and unimproved final road. There are no facilities; confirm road and weather conditions before committing to the route.

## Tools, limits, and season

- Tools: Hand digging tools may be used in already disturbed unconsolidated material. BLM explicitly prohibits tunneling because the soft material can collapse.
- Limits: Reasonable personal, noncommercial quantities only. Stay within the official collecting area and away from operations or claims.
- Season and current status: Open status is not a promise of safe access. Desert heat, cold, storms, mud, and military or land-use changes require a current check with the Fillmore Field Office.

## Conditions

- Never tunnel or undercut a bank.
- Keep people clear of the face while digging.
- Use only the authorized area and ordinary hand methods.
- Open geodes later in a controlled setting rather than creating flying fragments onsite.

## Geology

Geodes appear as hard rounded bodies in softer host material and commonly contain clear, purple, pink, or microcrystalline silica.

External roundness is only a clue. Many nodules are solid, and safe opening is required to see the interior.

## Field plan

1. Verify the current BLM route and restrictions.
2. Work only low, stable, previously disturbed material.
3. Remove loose material from above before reaching into a shallow face.
4. Stop if cracks, slumping, or undercutting appear.
5. Backfill and leave a stable surface.

## Safety

- Collapse is the defining hazard; tunneling is prohibited.
- Eye and hand protection are essential when handling or opening geodes.
- Carry emergency water, communications backup, and vehicle-recovery supplies.
