An Acceptable Number: Ten Men Underground at White Ash

By Gregg Patten

This book reconstructs what happened without dramatization, speculation, or moral judgment. Drawing from inspection reports, historical records, and the physical realities of coal mining along Colorado's Front Range, An Acceptable Number examines how reasonable decisions, made under known constraints, converged on irreversible loss.

The mine was inspected. The risks were understood. Limits were imposed. Work continued.

When failure came, it did not arrive as chaos, negligence, or villainy. It arrived as physics.

This is not a story about heroism or blame. It is a structural account of proximity, fire, water, pressure, and time-of how systems designed to function safely within margins can still exhaust those margins without warning.

Told in a restrained, archival voice, An Acceptable Number resists emotional instruction. It does not ask the reader to feel a certain way. It asks only that the sequence be understood.

The book begins and ends at the memorial plaque that marks the site today, where the names remain fixed and the ground has long since been reused.

The acceptable number was ten.
It remains ten.
