A Large Boulder The Size Of A Small Boulder
A Large Boulder The Size Of A Small Boulder is a Twitter catchphrase from a January 2020 roadblock warning by Colorado's San Miguel Sheriff account. The tautological description of a boulder was mocked and remixed heavily within 24 hours, turning a routine traffic alert into one of the most quoted lines of that week.
Overview
A Large Boulder The Size Of A Small Boulder is a phrasal gaffe from a January 2020 tweet by the San Miguel Sheriff's Office in Colorado, warning drivers about a rock blocking Highway 1451. The line reads as an unintentional tautology, comparing the boulder's size to another boulder rather than any useful reference object, and Twitter latched onto it almost immediately3.
The joke is entirely in the wording. The original photo shows a genuinely large rock sitting in a snowy road, so users spun the caption into shape jokes, identity gags, and captioned reaction posts within hours of the alert going out23.

The catchphrase is typically deployed as a reply or quote-tweet whenever someone describes an object by comparing it to itself, or as a caption on any photo of an oddly obvious hazard. A common convention is to swap "boulder" for the actual object while keeping the "[X] the size of a small [X]" structure intact for the joke to land.
