Overview
- Investigators from ATF, CBI, DFPC, the Boulder County Sheriff's Office and Nederland Fire have not determined origin or cause because the site remains too unstable to enter.
- Officials say heavy machinery is needed to stabilize debris, the structure will be removed to bare earth, and any rebuild must meet 2024 building codes.
- Authorities are asking anyone with photos or video from before, during or after the Oct. 9 fire to submit them to the Boulder County Sheriff's Office tip line or evidence portal.
- About 18 businesses were confirmed destroyed, including a sheriff's substation, medical and wellness offices, restaurants, retail shops and the Wild Bear Nature Center, which reported animal losses; no human injuries were reported.
- Gov. Jared Polis and Rep. Joe Neguse visited to coordinate assistance as leaders warned of significant economic impacts, and unaffected nearby sites remain limited or closed pending safety checks, with the B&F Mountain Market set to reopen Monday.
