At 8,800 years ago, the patterns of high-altitude use that would characterize later Rocky Mountain prehistory were still being established.

The specific territorial ranges, seasonal movement patterns, and community strategies that would develop over the following millennia were in their formative period.

In this context, the Hourglass Cave man represents an early episode in the long history of high-altitude human activity in the Colorado Rockies — not the beginning of that history, but one of the earliest well-dated and most dramatically documented moments in it.

His presence in the cave at high altitude, with artificial light, making a journey that required sustained effort and specific knowledge, is evidence of a human engagement with the high country that was neither casual nor accidental in its overall character, whatever the specific circumstances of his final entry into the cave.
