Green Burial Wyoming

For families who want a burial that's genuinely simple — a body returned to the earth without embalming chemicals, without a metal casket sealed in a concrete vault — Wyoming's legal framework is actually quite accommodating. The state doesn't mandate the practices that make conventional burial expensive and environmentally intensive. What stands between a Wyoming family and a natural burial is often not the law, but the policies of individual cemeteries. Understanding the distinction between what the state requires and what a cemetery may require on its own authority is the starting point for planning a green burial in Wyoming.

What Wyoming Law Does and Does Not Require

Wyoming state law does not require a burial vault or grave liner. This is a significant point: in many states, the assumption that a vault is required is so widespread that families accept it without question, not realizing it's a cemetery policy rather than a legal mandate.

The state also does not require embalming (see the Wyoming Funeral Law Guide for full details). There is no Wyoming regulation that compels a family to chemically treat a body before burial, choose a particular type of casket or container, or enclose remains in any outer burial container.

What Wyoming does require is the burial permit process: a death certificate filed within three days of death and a burial permit within 72 hours (W.S. § 35-1-420). The 36-hour rule also applies — remains must be refrigerated, embalmed, cremated, or buried within 36 hours of death. For families choosing natural burial without embalming, this typically means refrigeration during the period between death and burial.

Beyond those administrative requirements, Wyoming leaves the form of burial largely to individual choice.

The Cemetery Policy Question

Here's where families planning a green burial often encounter friction: while the state doesn't require vaults or liners, many conventional cemeteries do require them as a matter of cemetery policy.

Cemeteries adopt vault and liner policies for practical reasons. When a coffin deteriorates underground — which happens faster with natural materials — the ground above can settle unevenly, creating safety hazards for groundskeepers and unsightly surface irregularities. A concrete vault or liner maintains grade and makes cemetery maintenance more predictable.

A cemetery's right to set these policies is generally upheld — a cemetery is private property (or a legally established institution), and it can set its own rules for burial within it. The state not requiring a vault doesn't strip an individual cemetery of the authority to require one.

This means that if a family wants a natural burial in a conventional cemetery, the first step is to contact the cemetery directly and ask about their outer burial container requirements. Some cemeteries make exceptions; many do not. A frank conversation early in the process avoids discovering the conflict after arrangements are underway.

Green Burial Cemeteries and Natural Burial Grounds

The most reliable way to ensure a true green burial — unembalmed, biodegradable casket or shroud, no vault or liner — is to use a cemetery specifically designed for natural burial.

Wyoming's landscape includes properties operated or managed as natural burial grounds, often in rural settings. These cemeteries prohibit or don't require vaults, accept shrouds and biodegradable containers, and may prohibit embalmed remains to protect soil ecology. Some are operated as conservation burial grounds, where burial fees help fund land conservation in perpetuity.

The Green Burial Council certifies cemeteries at different levels based on how comprehensively they follow natural burial standards. A Hybrid Cemetery accepts natural burial in designated sections but also offers conventional burial elsewhere. A Natural Burial Ground prohibits vaults and pesticides and doesn't allow embalmed remains. A Conservation Burial Ground adds a third-party conservation commitment to the land.

Checking the Green Burial Council's directory is a reasonable starting point for families in Wyoming looking for certified providers, though not every natural burial cemetery in Wyoming will be listed there.

What a Natural Burial Looks Like in Practice

A green burial in Wyoming might involve:

The body. Unembalmed, washed and dressed by family members or a funeral home familiar with natural burial practices. The body is kept refrigerated until burial. Some families choose to keep the body at home for a brief period before burial — Wyoming law permits home vigils as long as the 36-hour refrigeration rule is observed if burial is not happening within that window.

The container. A shroud (natural fiber, typically linen or cotton), a simple wooden box made from untreated wood without metal hardware, or a wicker or seagrass casket. The FTC Funeral Rule protects your right to use any container you choose, and a funeral home cannot require you to purchase a casket.

The grave. No concrete vault or liner. The grave may be dug by family members on private property (with the county approvals required for home burial) or by cemetery staff at a natural burial ground. The depth requirements are those set by the specific location; state law doesn't prescribe grave depth.

The grave marker. Natural burial grounds typically use native rocks, plantings, or GPS coordinates rather than conventional headstones, which require manufactured materials and ongoing maintenance. Some families plant a native tree or shrub over the grave.

Scattering Cremated Remains: Wyoming's Rules

For families who prefer cremation but want an environmentally minimal approach, Wyoming has no state restrictions on where cremated remains may be scattered. Private land scattering is permitted with the property owner's consent. Scattering at sea (three nautical miles offshore) follows EPA marine guidelines.

Yellowstone and Grand Teton National Parks, which together cover a significant portion of northwestern Wyoming, require a free Special Use Permit for scattering ashes within park boundaries. The additional requirement is that scattering must occur at least 100 yards from any water source, trail, or road. The permit is free and the process is relatively straightforward — contact the relevant park's resource management office.

National forests and Bureau of Land Management land in Wyoming generally allow ash scattering without a permit, though some areas near water sources may have restrictions. Checking with the specific managing office before scattering in a particular location avoids potential issues.

Planning a Green Burial in Wyoming

If natural burial is important to you or a family member, the planning steps are:

1. Identify a cemetery or burial location that allows natural burial without vault requirements
2. If using private land, understand the county zoning and County Clerk map filing requirements
3. Confirm that the funeral home or death care provider you use is familiar with natural burial practices and won't require embalming or upsell unnecessary services
4. Ensure refrigeration arrangements are in place for the period between death and burial
5. Understand Wyoming's burial permit process, which applies regardless of burial type
