A bold political message reading “ICE OUT” briefly turned Boulder’s First Flatiron into a giant rock-side slogan early Thursday before crews scrubbed it clean within minutes. Sunrise hikers and photographers spotted the fresh paint and began sharing photos on local forums, where the sign’s blink-and-you-miss-it appearance and cleanup quickly bounced around community groups. The fleeting graffiti also revived conversation about the wave of anti-ICE demonstrations that swept the region earlier this year.

According to The Denver Post, the letters were first visible at about 7:40 a.m. on March 26 and were gone by roughly 8:00 a.m. Photographer Nicholas Reichert told the paper the message was up for less than 20 minutes. Images circulating online show the white-painted letters on the sandstone just before crews moved in to strip the paint and clean the face.

Rangers, Jurisdiction and Response

The Flatirons are managed by the City of Boulder’s Open Space & Mountain Parks, whose rangers patrol trails and rock formations on Green Mountain. According to the City of Boulder Open Space & Mountain Parks, those rangers act as first responders on open-space land and maintain nonemergency contact lines for reporting damage or hazards.

In a statement to The Denver Post, Jamie Barker said rangers were headed to the site when the paint was removed and that they “will try to contact the individuals involved.” Officials said there were no arrests or injuries reported as of Thursday morning, and the tight timeline left little opportunity for bystanders to intervene.

Local Protests Provide Backdrop

The “ICE OUT” message appeared amid a wave of anti-ICE demonstrations and memorial actions across Colorado that began in late January. Local reporting documented large marches and memorial rides in Boulder and Denver earlier this year, as covered by Boulder Reporting Lab and Colorado Public Radio.

OSMP staff said they will review photos and any witness accounts as part of their follow-up, and they asked anyone with information to contact open-space dispatch via the city’s OSMP page. The city emphasized that the Flatirons are protected natural resources and that crews routinely remove markings to protect both the rock and the surrounding habitat.
