The Flatirons, the venerable sandstone area in the Boulder Mountains, have long been a cornerstone in American rock climbing. People scrambled and established moderate multipitch routes here as early as the 1930s. Starting in 1985, some of America’s earliest sport climbs began to appear on their steeper flanks. They mainly climbed smooth, slabby faces on crimps and pebbles, with a few forays into overhanging terrain on pockets, cobbles, and huecos.
These early climbs departed from the status quo, from what we today call trad climbing. And routes had not always had the most imaginative monikers. First ascensionists often took cues from a climb’s geographic qualities (Northwest Corner) or the first-ascent party’s last names (Goss-Logan).
But the new wave of sport climbers had a chance to flex their creative muscles when naming climbs. These climbers wore garish Lycra leggings, tight tank tops, flashy, multicolored shoes, and neon chalk bags. Some brought boomboxes to the cliff and named some of their bolted climbs for lyrics, songs, or albums.
In the Flatirons, we had Violator (a 1990 Depeche Mode album), Superfresh (borrowing from rap terminology), and Slave to the Rhythm (a 1985 Grace Jones album and song).

Boulder native Dan Michael established Slave to the Rhythm in 1987. I first tried the route in 1991. It was already semi-famous for being so overhanging, the colorful rock peppered with tweaky pockets and a dizzying array of cobbles that made it barely climbable.
I didn’t return until 2014, 23 years later, when the route still had its original name. Slave to the Rhythm didn’t rub anyone wrong. But social-justice activism was in relative infancy at that point — at least in the climbing community.
In 2020, the climbing community at large pushed to change problematic route names. This was part of the society-wide movement to address social injustice and systemic racism, and to increase diversity, equity, and inclusion (DEI). The police murder of George Floyd turbocharged it. And Slave to the Rhythm, at least on Mountain Project, the most popular online route guide, became [Redacted], along with a slew of other climbs.
The censorship of route names grew exponentially over the next few years. An internal source at Mountain Project communicated that in August 2022, the site redacted over 6,000 route names. Perusing its database shows that some climbing areas had half or more of their route names redacted.
And the same source reported this week that there are almost 6,000 route names up for review in just one region of Mountain Project.
Have these redactions at Mountain Project and the movement to rename routes gone too far? Where is the line between harmful and just offensive? And should anyone other than the first ascensionist be able to change a route name?
