The Kildare Attribution — Three Arizona Caches, One Author

Case status: CLOSED — LEGEND. Updated August 2026. Treasure literature corroborates itself by repetition. A story appears once, gets retold in a compilation, gets retold again with the compilation as the citation, and after three cycles it reads as established history with several apparently independent sources behind it. Tracing derivation before counting agreement is the single most useful thing a researcher can do in this field, and almost nobody does it.

The shared author (SECONDARY). "Maurice Kildare" is a pen name of Gladwell Richardson, an Arizona writer who published lost-treasure material under roughly a dozen pseudonyms for pulp magazines in the 1960s and 1970s. True West, which published him, has publicly described him as well known for not letting the truth get in the way of a good story. Because the pseudonyms differ from case to case, stories that share a single author read as independent until the pen names are resolved.

Canyon Diablo 1881 — origin corrected (SECONDARY). The earliest traceable telling is M. Kildare, "Dead Outlaws' Loot," True West, Vol. 14, Jan–Feb 1967, pp. 16–19. That predates Richard Patterson's Historical Atlas of the Outlaw West (1985) by eighteen years, and Patterson had previously been treated — including on this site — as the origin. The verdict on the case was already LEGEND; what changes is why.

Mexican Pocket (UNVERIFIED). The twelve-man Valenzuela Gang, the pursuit by Sheriff Commodore Perry Owens, seven killed, two caches later recovered and ten presumed remaining all trace to Kildare in Long John's Treasure World, June–July 1973, and again in a 1978 lost-treasure magazine piece. No earlier source exists. A researcher put the story to Marshall Trimble, Arizona's official State Historian, who reported that he had never heard of it.

Rogers Lake (UNVERIFIED, and closed on the ground). Probert's bibliography lists two sources, "Kildare" and Penfield, and Penfield almost certainly took the story from Kildare — which makes it one source, not two. The named outlaws, "Henry Corey" and "Ralph Gaines," appear in no record located outside retellings of the story. The date moves between winter 1881 and winter 1891 across versions. Separately and decisively, Rogers Lake is a Coconino County Natural Area where metal detecting and treasure hunting are both prohibited by posted sign, with active enforcement.

Borrowed scaffolding (DERIVED). Both Mexican Pocket and the 1881 Canyon Diablo story attach an invented event to a real, heavily documented lawman or officer — Commodore Perry Owens in one, Capt. E.C. Hentig in the other. The verifiable name does the work of making the unverifiable claim feel checkable. A reader who checks the name finds a real person and stops checking.

What we removed. Every search area, coordinate, target zone and field recommendation attached to these three cases has been taken off this site. We do not direct anyone to ground on a case that fails source review. The pages remain published as documented negative findings.

Verdict. These are not three cases. They are one author, published three times, laundered into apparent consensus by compilers who cited each other rather than tracing derivation. All three cache claims are graded UNVERIFIED and closed as LEGEND. Reopening any of them requires a source that predates Kildare and is not derived from him — a period newspaper item, a court file, or a corporate loss entry. We carried two of these cases ourselves, and publishing that is the point of this page.
