Bradshaw Ranch & Secret Mountain — the Sedona UFO/portal lore

  • Type: case (lore-location cluster; alleged underground base / “portal” / orbs)
  • Place: Sedona, Arizona — the former Bradshaw Ranch (~12 mi from Sedona, between Hartwell and Loy Canyons) and Secret Mountain / Secret Canyon nearby
  • Why it matters: the canonical “vortex-town” UFO lore cluster — a place where decades of urban legend (underground base, interdimensional portal, tunnels to Skinwalker Ranch, men with M-16s, glowing orbs) has been revived in 2024–26 by credentialed-adjacent figures (Coulthart, Sheehan) and a commercial tour operator (Leslie). A clean test of separating a mundane, documented core from an un-provenanced extraordinary overlay.
  • Credibility: see assessment. The short version: the verifiable facts are prosaic (a former Hollywood movie-set ranch the US Forest Service bought); the extraordinary claims are uncorroborated, equipment-gated, or self-conceded unproven — even the tabloids covering the “tunnel” admit “no verified proof.”

The lore (what’s claimed)

A standing Sedona legend, per the local paper’s own summary: “underground military tunnels, helicopters disappearing in Secret Canyon, men in black, camouflaged military with M-16 rifles chasing away hikers, UFO sightings… strange lights… pseudo-portals to parallel universes.” Its load-bearing pieces:

  • A 1950s deep-underground military base under Secret Mountain — pushed by Ross Coulthart (“I am in no doubt whatsoever”) and Danny Sheehan (“an alien base under Secret Mountain”).
  • The Bradshaw Ranch “portal” — an alleged interdimensional opening in the ground, said to have been photographed by ranch resident Linda Bradshaw; the fenced-off spot reportedly has a solar-powered camera pointed exactly at the portal site and hidden three-phase power (per Coulthart).
  • Glowing “plasmatic” orbs over Secret Mountain at ~1:30 a.m., escorted by fleets of Black Hawks (Coulthart’s firsthand claim — seen through Melinda Leslie’s night-vision goggles).
  • A tunnel linking Sedona to Skinwalker Ranch — alleged GPR scans of a “straight underground structure” toward Clarkdale.

The verifiable core (what’s actually documented)

Strip the overlay and the documented facts are mundane:

  • Bradshaw Ranch was a 90-acre working movie set, bought in 1960 by Bob Bradshaw, a Hollywood stuntman; it hosted five Western films, two TV series, and commercials.
  • The paranormal claims originate with a 1995 believer bookMerging Dimensions: The Incredible Saga of Bradshaw Ranch, by Bob’s wife Linda Bradshaw and UFO author Tom Dongo — dating the orbs/beings to 1992.
  • Bradshaw sold the land to his own Jeep-tour company for 3.15M, 2001) — which is why it sits fenced and closed today (federal land management, not a secret base).
  • In Dec 2022 the History Channel filmed Beyond Skinwalker Ranch there (investigators Andy Bustamante, ex-CIA, and journalist Paul Beban; tied to Brandon Fugal’s Skinwalker franchise).
  • The Bradshaw family is non-committal-to-skeptical: son John Bradshaw (former Sedona vice-mayor) — “these are conspiracy theories… I need to see it with my own eyes before I believe it.”

What’s solid vs. unresolved

  • Solid: a former movie-ranch, a 1995 believer book, a 1998 sale, a 2001 Forest-Service purchase, a 2023 cable-TV shoot, and a town whose vortex/UFO tourism identity rewards the lore.
  • Unresolved / unverifiable: the underground base, the portal, the tunnel, the orbs. Every extraordinary element is un-provenanced; the orbs are equipment-gated (visible only through Leslie’s goggles, unrecordable — see the “are the goggles rigged?” thread); and the tunnel is conceded unproven even by the tabloid promoting it (“no verified proof”).

Credibility assessment

Treat Bradshaw Ranch / Secret Mountain as the textbook lore-location: a real, ordinary place (movie ranch → Forest Service land) onto which decades of unfalsifiable narrative have been layered and recently re-platformed by name-brand figures. The pattern is the Ubatuba problem in geographic form — the closer you look, the more the documented core shrinks to the mundane while the dramatic claims rest on anonymous testimony, a believer book, equipment-gated sightings, and “fenced-off federal land = secret base” inference. Closures and cameras on Forest-Service land have an obvious prosaic reading; “men with M-16s on public trails” is the kind of anonymous, uncheckable detail the evidence framework treats as non-evidence. Cite Sedona as the canonical example of UFO lore fused to a tourism economy (the Leslie tours, the Jeep tours, the History Channel shoot all monetize it) — not as evidence of a base, a portal, or a tunnel. The 2026 revival (Coulthart, Sheehan) is old lore acquiring new credentialed amplification, not new evidence. (Plasma framing of the orbs: plasmoids-and-plasma-life.)
