A Jar on a Sealed Doorstep: What's Watching Shaft Four?
A sealed assay office, untouched for decades, and on one February morning a fresh glass jar sits on the doorstep with a handwritten label: "Shaft Four - 340 feet - February." The jar contains four ounces of rust-colored chalcopyrite-bearing andesite, the cork and iron gall ink look decades-old, yet the jar shows none of the dust that coats every interior surface - so who placed it, and how did it arrive without disturbing a sealed building?
In this episode, we lay out the recorded evidence, witness timelines, and material analysis from Coldwater Bench to let the facts speak for themselves, asking whether the jar is a deliberate message, a misplaced artifact, or something else that points three hundred forty feet down.
Person: Thomas Adams, 54-year-old retired letter carrier from Elko, Nevada
Date: February 3, 2011 (jar discovered at 6:40 a.m.)
Location: Coldwater Bench assay office, Mineral County, Nevada
Case: Jar labeled "Shaft Four - 340 feet - February" placed on sealed doorstep
Object: Glass jar containing ~4 ounces of chalcopyrite-bearing andesite with cork stopper and iron gall ink label
- Thomas Adams photographed the jar with 37 photos before touching it, noting the doorstep had been clear in his January 2009 photograph.
- The assay office had last authorized entry for a subsidence survey in September 2010, five months before the jar appeared.
- Every jar on the interior wall rack was uniformly coated in fine white dust, while the jar from the doorstep showed no dust.
- Laboratory analysis identified the powder as chalcopyrite-bearing andesite consistent with the Sulphur Creek formation.
- The jar's glass style, natural bark cork, and iron gall ink are consistent with early twentieth-century manufacture and materials.
