Last access and rule review: September 18, 2026
Page purpose: Original LithoMap trip-planning reference for an explicitly authorized rock, mineral, or non-dinosaur fossil collecting destination.

## Direct answer

A remote BLM desert district long used for geode hunting, approached by graded dirt roads whose condition changes after rain and maintenance.

## Location and material

- State: California
- Area: Colorado Desert west of Blythe
- Category: Rock collecting
- Collection status: Collecting allowed
- Expected material: Geodes, Quartz, Chalcedony

## Authorization

BLM identifies the Wiley Well District Geode Beds as a public recreation destination. Casual collection still requires confirmation that the exact ground is open BLM land and outside claims, wilderness, protected sites, and closures.

## Access

The approach south from Interstate 10 becomes graded dirt and can be badly washboarded or impassable after rain. Contact the El Centro Field Office for current route and land-status information.

## Tools, limits, and season

- Tools: Use hand tools only where casual collection is currently permitted. Motorized or mechanical collecting devices are not allowed under California casual-use guidance.
- Limits: California BLM guidance sets a general personal-use ceiling of 25 pounds plus one piece per day and 250 pounds per calendar year, unless a site-specific rule is more restrictive.
- Season and current status: Winter is generally cooler, but rain can make the road unsuitable. Summer desert heat can be life-threatening.

## Conditions

- Verify land status and claims before collecting.
- Stay out of wilderness and protected cultural or fossil sites.
- Use no motorized collecting device.
- Keep within the current personal-use limit.

## Geology

Silica-rich nodules and geodes occur in the broader desert volcanic terrain.

A rounded exterior does not guarantee a hollow or crystal-lined center; open specimens later with controlled equipment.

## Field plan

1. Call the field office and download current maps.
2. Check weather and road conditions.
3. Confirm the exact open BLM parcel.
4. Surface search before shallow hand work.
5. Pack out all waste and open geodes at home.

## Safety

- Road condition and remoteness are major hazards.
- Flash flooding and extreme heat can strand visitors.
- Carry extra water, fuel, tire equipment, and offline navigation.
