American Alchemy / Jesse Michels ↗YouTube-hosted preview and player; not relicensedA former ranch and documented NAU ecological research site near Sedona. Coulthart proposes an underground connection, but the original follow-up instrument account is narrower than his later 50-foot-wide tunnel description. His separate too-large-to-move UFO story has no disclosed location.
Read the full account
NAU published metadata for plant surveys conducted here in May–July 2017. The research-site coordinates are published with that dataset; they do not locate an alleged tunnel.
In the May 2025 NewsNation segment, an already proposed tunnel alignment guides a small follow-up survey. Operator Paul Duggan describes uncertain shallow features. Coulthart’s later description of a 50-foot-wide reinforced tunnel is not demonstrated by that segment. Width, depth and survey footprint must remain separate.
The huge, immovable UFO discussed later in the American Alchemy interview is an unlocated claim, not a Bradshaw discovery.
Source review, September 2026: Read the fixed-locations investigation for the obtained records, source differences and remaining tests.

An opening montage juxtaposes Secret Mountain and the remote-viewing base narrative. This excerpt does not establish Secret Mountain as one of Price’s original four targets; those are Hayes, Zeil, Perdido and Nyangani.

Coulthart describes a 50-foot-wide reinforced structure near the surface. This is his interpretation; the original published follow-up describes a roughly three-foot scan footprint and uncertain features, not a demonstrated 50-foot tunnel.

He did a ground penetrating radar check on the road around Bradshaw Ranch, and we found a 50-ft wide reinforced steel concrete, highly visible on ground penetrating radar. Literally just under the ground. Wow. I mean, I'm in no doubt whatsoever it's there. Can you get down
