An early morning shockwave that was heard and felt around the Keno and Round Lake areas early Saturday morning in Klamath County is under investigation.

Keno residents reported a loud “shockwave” followed by a column of smoke around 1:33 am on Saturday morning. Residents reported the “shockwave” waking them up and even shaking their houses. A person who lives at Round Lake reported to Klamath Alerts that the “shockwave” was heard there as well.

Theories of the source circulated on social media….they ranged from UFO’s, meteors, supersonic aircraft, and even a natural gas explosion.


Later Saturday morning a hole in the old Weyerhauser bridge was found by local residents and this offers a likely explanation of the source of the “shockwave”. It appears that someone may have blasted the bridge with an explosive device. There is currently no confirmation from law enforcement on the cause.

The Klamath County Sheriff’s Office told Klamath Alerts that they are aware of the incident and it is currently under investigation. This is a developing story and it will be updated if additional information becomes available.
