Falcon Lake
On the afternoon of 20 May 1967, Stefan Michalak — a 51-year-old industrial mechanic from Winnipeg — was prospecting for quartz veins in Whiteshell Provincial Park near Falcon Lake, Manitoba when he observed two large red disc-shaped craft. One landed on a flat rock approximately 50 m from his position; the other departed vertically. Michalak approached the landed craft, observed it for approximately 30 minutes, and attempted to inspect a doorway in its side. The craft rotated; a panel of vents on its side discharged a blast of hot exhaust onto Michalak's chest, igniting his shirt and producing a geometric grid-pattern burn over his upper torso. The craft departed vertically. Michalak walked ~25 km out of the bush to the Trans-Canada Highway, was taken to Winnipeg, and was admitted to Misericordia Hospital with severe nausea, vomiting, headache, and the chest burns. The Royal Canadian Mounted Police, Royal Canadian Air Force, and Department of National Defence conducted joint investigations; the case file at Library and Archives Canada remains officially classified as "unknown".
The medical record
Michalak presented at the Misericordia General Hospital emergency department, Winnipeg, in the late afternoon of 20 May 1967. Admitting physician Dr. Felix Loewy documented: first-degree chest burns in a precise grid pattern, severe nausea, persistent vomiting, headache, and a marked drop in blood lymphocyte count over the following 72 hours — a clinical picture consistent with acute radiation exposure compounded by thermal burn. Subsequent examinations were conducted by Dr. Horace Dudley (radiation specialist, Wayne State University) and by physicians at the Mayo Clinic in Rochester, Minnesota, where Michalak travelled for follow-up care between 1967 and 1968. The Mayo records — preserved in the Michalak personal medical file at LAC — document persistent grid-pattern dermatographic anomaly on the chest for at least 18 months post-event.
What the official investigation found
RCMP Winnipeg detachment opened file 67-1167. Cpl. Glen Davis led the on-site investigation; a geological + radiation survey was conducted at the landing site by RCAF + DND specialists on 22-25 May 1967. Findings: (1) An elliptical scorched area approximately 4.5 m by 3 m on the flat rock at the indicated landing site. (2) Elevated radioactivity in samples taken from the centre of the scorched area — radium-226 levels approximately 3x background, requiring the area to be temporarily fenced. (3) A silver-coloured metallic flake approximately 1 mm thick recovered from the burn pattern on Michalak's shirt; spectrographic analysis by the Canadian Department of Health identified the flake as silver-bearing alloy with anomalous trace elements not matching any then-known industrial alloy.
Why this case still matters
Falcon Lake is the most thoroughly medically + forensically documented UAP injury case in any government's records. The combination of (1) a credible single witness with no motive for fabrication; (2) a contemporaneous Canadian-government investigation involving RCMP + RCAF + DND + Department of Health; (3) the physical recovery of an anomalous metallic flake; (4) the persistent grid-pattern dermatographic anomaly documented by U.S. Mayo Clinic physicians; and (5) the elevated radium-226 at the landing site — makes the case unique. The Royal Canadian Mint, in 2018, issued a commemorative C$20 silver coin marking the 50th anniversary of the event. The complete file at LAC (RG 18 RCMP + RG 24 DND + RG 33 Department of Health) is publicly accessible.

C$20 silver coin — Falcon Lake 50th anniversary, 2018
Government-of-Canada-issued commemorative coin marking the event. The only case in any government's UAP record that has been formally commemorated by national-mint issuance.
Why this case still matters
Falcon Lake is the most thoroughly medically + forensically documented single-witness UAP injury case in any government's records. The unique combination of contemporaneous Canadian-government investigation, U.S. Mayo Clinic medical follow-up, elevated radium-226 at the landing site, and the recovery of an anomalous metallic flake makes it the canonical reference for the physical-trace + anomalous-physiology category. Royal Canadian Mint's 2018 commemorative coin is the only case of formal national-government commemoration of a UAP event in modern records.
