See it: Car-sized boulder falls onto a Colorado highway
A boulder roughly the size of a small car crashed onto a Colorado highway Saturday, partially blocking traffic and creating an impromptu spectacle.
The San Miguel County Sheriff’s Office said the rockfall occurred on Colorado Highway 145 at mile marker 75, not far from the Telluride Regional Airport in the southwestern portion of the state.
No injuries were reported, but the road obstruction caused minor traffic backups as vehicles slowly maneuvered around the debris.
