PURSUE Record — Skinwalker Ranch — Uintah Basin, Utah (1990s–present): Private (Bigelow / NIDS / BAASS) + later AAWSAP / AATIP government interest · Sherman Ran

The record titled Skinwalker Ranch — Uintah Basin, Utah (1990s–present) is a historical file (type: HIST) included in the May 8, 2026 PURSUE Release 01 by the U.S. Department of War. It does not originate from a single military sensor event or a discrete flight encounter. Instead, it represents the official documentary footprint of a sustained, multi-decade anomalous phenomena investigation at a private property in the Uintah Basin — an investigation that eventually entangled both private aerospace money and classified U.S. government research funding.

What this record contains

The releasing agency is listed as Private (Bigelow / NIDS / BAASS) with later AAWSAP / AATIP government interest, reflecting a layered chain of custody unusual even within the PURSUE Release 01 catalogue. The incident location is Sherman Ranch, Uintah Basin, Utah — a property that sits on the border of Ute Tribal lands. The documented timeframe is the 1990s to the present, making this one of the longest active case windows in the release. The public release consists of a single file part.

The official description blurb states that the ranch has been the site of "reported anomalous phenomena including unidentified craft, animal mutilations, and unexplained physical events since the early 1990s." Mainstream coverage began with a 1996 Salt Lake Tribune report. Robert Bigelow purchased the property that same year and funded the National Institute for Discovery Science (NIDS) and subsequently Bigelow Aerospace Advanced Space Studies (BAASS) to conduct on-site investigation. BAASS later received the DIA-administered AAWSAP contract — the Advanced Aerospace Weapon System Applications Program — which funded what became the AATIP program and the institutional precursor to the current All-domain Anomaly Resolution Office (AARO). The property was sold to Brandon Fugal in 2016 and has since been the subject of a History Channel documentary series.

Sensor & operational context

Unlike the sensor video records or NASA archive imagery elsewhere in PURSUE Release 01, this HIST-type record does not originate from a calibrated government instrument pointed at a discrete target on a known date. The evidentiary basis here is investigative documentation accumulated over roughly three decades by a succession of private and government-contracted research teams. NIDS, operating through the late 1990s and 2000s, applied structured scientific methodology — cameras, magnetometers, and field investigators — to a location that generated recurring reports from the Sherman family before Bigelow's purchase. BAASS extended that instrumentation under a formal DIA contract, which means some portion of the underlying documentation carries the classification and handling standards of a government intelligence program, even though the property itself remained privately owned.

The AAWSAP-to-AATIP lineage is significant to the record's placement in this release: it is one of the clearest documented cases in which a private investigation site fed directly into the formal U.S. government UAP research infrastructure that eventually produced AARO. The transition of the property to Brandon Fugal in 2016, and the subsequent media production activity, added a further layer of public documentation that the single-part file in this release does not appear to fully encompass.

What this does and does not prove

What the record establishes, based solely on its metadata, is that multiple organized entities — private, contractor, and government-funded — directed formal investigative resources toward this location over an extended period, and that the Department of War considered that investigative history relevant enough to include in a declassified release. It does not establish that any specific anomalous phenomenon occurred, was confirmed by calibrated sensor, or was attributed to a non-human intelligence. The reported phenomena described in the official blurb — unidentified craft, animal mutilations, unexplained physical events — are characterizations drawn from witness reports and investigative records; the release does not adjudicate them. The public release does not include detailed metadata beyond what is noted above, and the single file part's full contents are not enumerated in available release documentation. Uncertainty here is not a rhetorical hedge — it is the accurate description of the evidentiary state.

How it fits PURSUE Release 01

Within the 162-document PURSUE Release 01 set — spanning 28 videos, 14 images, and 120 PDFs — the Skinwalker Ranch HIST record occupies a distinct category: it is not a discrete military encounter report, an FBI archive field investigation from the 1947–1968 era, or a frame from a NASA optical or infrared camera. It is instead the institutional record of how a single geographic location became a recurring focal point for the U.S. government's UAP research apparatus, bridging private funding, a DIA contract, and the AATIP-to-AARO lineage that gives the entire PURSUE project its institutional context. That lineage alone justifies its inclusion, regardless of what the underlying file ultimately contains.
