One mile southwest of Socorro, New Mexico, the ground still holds marks. Four rectangular depressions, each roughly sixteen by six inches. They were there in April 1964. A newly declassified FBI file, released May 8, 2026, confirms they were observed and documented.
The document, Serial 438 from the FBI’s UFO case files, does not explain what made those impressions. It describes them. Regular in shape. Sixteen by six inches. Rectangular. That specificity matters. It is not a vague scorch mark or a crushed bush. It is a precise geometric pattern pressed into rough ground.
What is at stake here is not belief. It is documentation. The FBI had a man on site within hours. Special Agent D. Arthur Byrnes Jr. was in the Socorro State Police Office on routine business the late afternoon of April 24, 1964. He was not chasing a story. He was there for other work. He learned of the incident from a radio operator named Nep Lopez, who walked into the office and told M.S. Chavez of the New Mexico State Police that Officer Lonnie Zamora had radioed for help. Zamora said an unknown object had landed and taken off.
Byrnes knew Zamora intimately for five years. He described him as sober, industrious, conscientious, not given to fantasy. Byrnes found Zamora at the site around 6:00 p.m., along with Undersheriff Jim Luckie, Sergeant Chavez, and Officer Ted Jordan. Byrnes noted Zamora was perfectly sober and somewhat agitated.
Agitated. Not drunk. Not confused. Not lying.
The file does not contain Zamora’s full statement. It contains what a federal agent saw with his own eyes and heard from a man he trusted. The ground impressions were there. Four of them. Regular. Rectangular. Sixteen by six inches. That is a physical fact, not a recollection.
The stakes are simple. If four regular rectangular depressions appeared in rough ground in Socorro in 1964, and a sober police officer reported an object landing and taking off, and an FBI agent who knew the officer for five years confirmed the man was credible, then the question is not whether something happened. Something happened. The question is what.
The file is part of the U.S. Department of War’s PURSUE archive. It was classified for 62 years. It was released because the government decided it could be. That decision carries weight. Documents held that long are not released carelessly.
There is no explanation in the file for the impressions. No natural cause is offered. No weather event. No animal. No hoax. Just the record of a federal agent who drove to a site, looked at the ground, wrote down what he saw, and filed it.
Socorro is not a place known for spectacle. It is a town. A police officer worked there. He called for help. Other officers came. An FBI agent came. They stood on rough ground and looked at four rectangular holes. Then they wrote it down.
The file is 7.2 megabytes. It is a PDF. It exists now because someone decided it should. The impressions in the ground are gone. The document is not.
