Skinwalker Ranch

Briefing

Skinwalker Ranch is a 512-acre property on the Uintah and Ouray Reservation in north-eastern Utah. For thirty years it has been the most intensively investigated paranormal site in the United States, and it has produced almost no evidence that anyone outside the investigations can check.

That sentence is the case file. Two things are true at once, and most accounts carry only one of them. A great deal has been claimed at this property, by named people, in consistent terms, over three decades. And essentially none of it exists as data that a third party can examine. The one part of the story that does rest on documents is not about lights or cattle at all. It is about money.

The ranch is private property with no public access, and trespass is prosecuted.

Sequence of events

1994–1996 — the Sherman family

Terry and Gwen Sherman bought the property in 1994 and worked it as a cattle ranch [2]. Over roughly eighteen months they reported a sustained pattern of events: livestock vanishing or found dead with precise incisions and no blood, large unidentified animals that did not behave as animals, and lights moving over the pastures [2][5].

The record begins properly on 30 June 1996, when the reporter Zack Van Eyck published the family’s account in the Deseret News [2]. By that reporting the family had lost four cows outright and found three more mutilated. Terry Sherman raised the possibility that what they were seeing was a classified government project [2]. The Shermans sold shortly afterwards, having owned the ranch under two years.

The sceptical reading is on the record too: the writer Robert Sheaffer has suggested the account may have been constructed ahead of a sale. Local authorities are reported not to have received formal complaints matching many of the alleged incidents.

1996–2004 — NIDS

The buyer was Robert Bigelow, the Las Vegas property magnate who later founded Bigelow Aerospace. He bought it through his National Institute for Discovery Science (NIDS), founded in 1995 to study such claims with scientific method [5].

NIDS put instruments and staffed observation on the property for several years under the biochemist Colm Kelleher. What that programme concluded is best taken from Kelleher himself [7]:

• The team logged close to 100 incidents, counting events reported before NIDS arrived as well as during.
• “The one thing that jumps out is how unreproducible they are.”
• On the calf found dismembered in March 1997, he said the complete absence of blood was “difficult to explain without invoking some extraordinary circumstances”.
• He reported witnessing “orbs” of light he “found difficult to explain”, and instrument readings he could not resolve — “sharp transient spikes” on Trifield meters that survived repeated recalibration.
• And the limiting admission: it was “very difficult to gather the kind of evidence consistent with scientific publication”.

NIDS wound down in October 2004. Kelleher has said reported activity fell away sharply from about 2000. The popular account of this period comes from Hunt for the Skinwalker (2005), written by Kelleher with the journalist George Knapp [5]. It is the source of nearly everything the public believes about the ranch, and it is a first-person narrative by participants, not a dataset.

One contemporaneous note cuts against it: the astrophysicist and UFO researcher Jacques Vallée is reported to have recorded in his private diaries that there were no UFO sightings at the ranch in 1996, 1997 or 1998 — the opening years of the NIDS watch. We have not read the diary entry directly and flag it below.

2007–2012 — the Pentagon years

This is the documented part.

In 2007 a Defense Intelligence Agency official, James Lacatski, visited the property and met Bigelow [6]. The Defense Appropriations Acts of Fiscal Years 2008 and 2010 appropriated $22 million to the DIA — in AARO’s words, “to assess long-term and over-the-horizon foreign advanced aerospace threats to the United States” [1][3]. The money came at the direction of Senate Majority Leader Harry Reid.

In 2009 the DIA established AAWSAP — the Advanced Aerospace Weapon System Applications Program — and contracted it to a private sector organisation. That organisation was Bigelow’s, and the property it studied was his own ranch. AARO states this plainly [1]:

“Although investigating UFO/UAP was not specifically outlined in the contract’s statement of work, the selected private sector organization conducted UFO research with the support of the DIA program manager.”

What the programme looked into at the ranch, again in AARO’s words [1]: “an alleged hotspot of UAP and paranormal activity at a property in Utah — which at that time was owned by the head of the private sector organization — including examining reports of ‘shadow figures’ and ‘creatures,’ and exploring ‘remote viewing’ and ‘human consciousness anomalies.’” The organisation “also planned to hire psychics to study ‘inter-dimensional phenomena’”.

On 24 June 2009 Reid wrote to Deputy Secretary of Defense William J. Lynn III asking that the programme be given Special Access Program status [1][4]. The request was refused, on the recommendation of James R. Clapper Jr., then Under Secretary of Defense for Intelligence, who judged that it was not justified [1].

The programme was terminated in 2012. AARO’s verdict on the Department’s own involvement is unambiguous [1]: “DIA did not seek, nor specifically authorize, this work though a DIA employee set up and managed the contract with the private sector organization.”

And the least-covered item in the whole file. Shortly before cancellation the contractor proposed a public-engagement campaign of “intellectual debates” at academic institutes “which included hiring supportive reporters and celebrity moderators”, premised on the position that “E.T. visitations are true”, with moderators steering discussion away from “dead-end discussions” and the “morass” about discussing “evidence” [1].

A government contractor proposed paying journalists to steer the public away from discussing evidence. It is in the official history, and it is almost entirely absent from popular coverage.

2016 to the present — Fugal and television

Brandon Fugal, a Utah commercial property developer, bought the ranch from Bigelow in 2016, initially through a shell company, Adamantium Real Estate, keeping his identity private until the History Channel series was commissioned. Fugal has described buying it as a sceptic who expected to debunk the claims.

The Secret of Skinwalker Ranch premiered in March 2020 and has run for six seasons, with a seventh announced for 2026 [9]. Fugal is an executive producer and appears in it. The on-site science is led by the aerospace engineer Travis Taylor.

The series has made the ranch globally famous and has produced no peer-reviewed publication. The structural criticism is not that the people in it are dishonest but that the format is adversarial to the method: results arrive as cliffhangers, and cliffhangers are not findings.

Documentary record

It is worth being precise about which parts of this story have documents behind them, because the proportion is small.

Documented. The AARO report of February 2024, pages 22–23, and every quotation above drawn from it [1]. The appropriations themselves [3]. The Reid letter of 24 June 2009 and its refusal [1][4]. The Deseret News report of 30 June 1996, which documents that the claims were made in 1996 — not that they were correct [2]. The chain of ownership.

Testimony. Everything in Hunt for the Skinwalker and Skinwalkers at the Pentagon [5][6]. Kelleher’s interview statements [7]. These are accounts by named, identifiable, professionally credentialled people, given consistently over decades. That is worth something. It is not the same as data.

Privately held, unreleased, or absent. The NIDS instrument record. The AAWSAP material relating to the ranch. The present-day measurements shown on television. None of it has been released in a form permitting independent replication.

Two verdicts from the primary source are blunter than anything a sceptic has written [1]: the programme’s scientific papers “were never thoroughly peer reviewed”, and AARO “has yet to uncover any other substantive UAP case work conducted by AAWSAP/AATIP”. The ufologist Barry Greenwood, writing in the Journal of Scientific Exploration in 2023, made the same point about the ranch specifically — no documentary evidence after decades of investigation [8].

The naming correction

Most coverage of this subject contains the same error, and it is worth isolating.

The $22 million is routinely credited to AATIP. It was AAWSAP. AARO states [1]:

“The names AAWSAP and AATIP have been used interchangeably for the name of this program, including on official documentation. Unlike AAWSAP, AATIP was never an official DoD program. However, after AAWSAP was cancelled, the AATIP moniker was used by some individuals associated with an informal, unofficial UAP community of interest within DoD… This effort was not a recognized, official program, and had no dedicated personnel or budget.”

This is contested by the people who were there. Skinwalkers at the Pentagon states under its own heading “AAWSAP Was Not AATIP” that these were separate efforts [6]. Lacatski has separately said AATIP was a nickname for AAWSAP adopted for security reasons — which does not agree with his own book.

The official history and the insiders’ account disagree, and one insider disagrees with himself. We report the disagreement; we do not adjudicate it.

Open questions

1. The Vallée diary entry. Reported to record no UFO sightings at the ranch in 1996–1998. We have not read the primary and have not cited it as established.
2. The NIDS data. Instrument logs from 1996–2004 have never been published. Whether they survive, and who holds them, is unknown to us.
3. The AAWSAP ranch reporting. AARO says it has not found substantive case work. Whether that means it was not produced or has not been located is not resolved in the report.
4. The Defense Intelligence Reference Documents. A set of papers produced under the contract is widely cited as numbering 38. We have not read the DIA list and do not assert the number.
5. Programme dates. Sources give AAWSAP as 2008–2010 and 2009–2012. We use AARO’s own dates, 2009–2012 [1].

Status

Open. The phenomena claims are unverified and, on the present evidence, unverifiable by anyone outside the private investigations that hold the data. The funding history is settled and documented.

One correction to the primary source, noted for accuracy rather than effect: AARO’s report names “Senate Majority Leader Harry Reid (D-NM)” [1]. Reid represented Nevada for thirty years. It is a trivial slip in an otherwise careful document, and it should not be inflated into an argument that the document is unreliable.
