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

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

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 book — Merging 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 $2.75M (1998); the US Forest Service acquired it (~$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").

A 2026 on-site field investigation (Uncanny Expeditions)

The first evidence-based, boots-on-the-ground check of these claims in this base is a June 2026 field investigation by the YouTube channel Uncanny Expeditions (../raw/transcripts/uncanny-expeditions-sedona-base-field-investigation-2026-06-24), which physically visited all three load-bearing sites (Sycamore Canyon, the Clarkdale cement plant, Bradshaw Ranch) with night vision, thermal, a drone, and ADS-B. It is skeptical but careful, and it corrects specific factual claims in the Coulthart series while conceding a residual.

What it debunks, with checkable specifics:

  • The orbs are satellites and aircraft. The lights filmed on the Sedona UFO tours move linearly and brighten in a fixed flare window — the signature of low-Earth-orbit satellites — or are aircraft landing lights, which night-vision tubes (PVS-14) render artificially orb-like. His practical test: a true satellite shows nothing on a thermal imager, whereas an aircraft rising from a canyon would; the tour narration ("amber means an ionized field") is physics word-salad.
  • The cement-plant ownership claim is wrong. The NewsNation segment slid from "owned by Martin Marietta Materials" to "Lockheed Martin," but the two separated in 1996 and are unrelated, and the Clarkdale plant is owned by neither — it belongs to the Salt River Materials Group, a venture of the Salt River Pima-Maricopa Indian Community, not a defense contractor. Martin Marietta owns only a neighboring ready-mix facility, and only since 2021, decades after the alleged tunnels.
  • A key "photo of the secret base" is a public observatory. Jeremiah Horstman's image of an "unmarked road access" to the alleged base is the clearly-signed entrance to the Naval Observatory Flagstaff Station, identifiable on Google Street View.
  • Bradshaw Ranch's real tenant is documented and prosaic. The fenced site hosts the Southwest Experimental Garden Array (SEGA), run by Northern Arizona University under a Forest Service special-use permit; on site he found abandoned buildings, downed fencing, a camera pointed inward at the buildings rather than outward, no threatening signage, and the only "security response" of the night turned out to be a UFO tour group.

What it honestly leaves open: he does not land on "pure hoax." A couple of ordinary hikers independently told him they saw Blackhawk helicopters appear to land in Sycamore and Secret canyons, and a former co-worker, unprompted, described black helicopters landing at the "quarry near Jerome" (the same Clarkdale cement plant) plus out-of-place security in an F-150. Military helicopter traffic is not itself unusual here (the Sedona airport holds a military refueling contract; nearby Camp Navajo runs helicopter training), but he could not explain why Blackhawks would land at a privately-owned cement plant. His conclusion: decades of smoke and mirrors may conceal a small kernel of ordinary clandestine-activity truth — stay curious, remain skeptical, evidence-based.

It is the most useful single source on the cluster precisely because it is neither credulous nor dismissive: it dismantles the specific extraordinary claims (the Lockheed-owned tunnel front, the orbs, the secret-base photo) on checkable grounds, and isolates the one prosaic anomaly worth a second look — unexplained military rotary-wing activity — which is a far smaller claim than an alien base under Secret Mountain.

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: ../topics/plasmoids-and-plasma-life.)
