For years, conditions inside the United States’ only federal supermax facility were largely a mystery. But a landmark lawsuit is finally revealing the harsh world within.

It was designed to be escape-proof, the Alcatraz of the Rockies, a place to incarcerate the worst, most unredeemable class of criminal — “a very small subset of the inmate population who show,” in the words of Norman Carlson, the former director of the Federal Bureau of Prisons, “absolutely no concern for human life.” Ted Kaczynski and the Atlanta Olympics bomber Eric Rudolph call the ADX home. The 9/11 conspirator Zacarias Moussaoui is held there, too, along with the 1993 World Trade Center bombing mastermind Ramzi Yousef; the Oklahoma City bomber Terry Nichols; the underwear bomber Umar Farouk Abdulmutallab; and the former Bonanno crime-family boss Vincent Basciano. Michael Swango, a serial-killing doctor who may have poisoned 60 of his patients, is serving three consecutive life sentences; Larry Hoover, the Gangster Disciples kingpin made famous by rappers like Rick Ross, is serving six; the traitorous F.B.I. agent Robert Hanssen, a Soviet spy, 15.
