This is Aron Ralston’s account of an experience that occurred while he was severely dehydrated, physically depleted, and alone in a dark canyon. It cannot be independently corroborated; it is his testimony about an internal event. What can be noted is that it was consistent with the actual future: he did eventually have a son. The vision depicted him with one arm, a detail he has noted was more accurate than the film adaptation, which showed him with two arms in the equivalent scene.
The vision does not explain in any mechanical sense why he survived. What it appears to have done is crystallize a decision that the preceding days had been building toward. He had already been testing whether his multi-tool could cut through skin. He had already accepted that the boulder was not moving. The vision seems to have resolved a remaining hesitation — converted a logical conclusion about what was necessary into an emotional commitment to carry it out.
He made his plan.
## Thursday, May 1, 2003: The Decision and Its Execution
The morning of Thursday, May 1, 2003, was the sixth day of Aron Ralston’s entrapment and the day on which he acted.
What he did has been described in various accounts with varying levels of detail, and the prompt for this article specifically requires that it be handled at a high level, without procedural description of the steps involved. What follows honors that requirement. The broad factual outline is: Ralston used mechanical force — the leverage of his own body against the position of his trapped arm — to break the bones of his forearm. He then used his multi-tool to complete an amputation, a process that took approximately an hour. He improvised a tourniquet and a sling using equipment he had brought into the canyon.
