I heard it around 1 p.m. on a hiking trail a few miles north of Saranac Lake, NY. I thought it was the gate of a dump truck from a nearby quarry so I dismissed it. Later, when I heard the sound of low flying jets in such an underpopulated area I thought again about that boom. Apparently, I wasn't alone in thinking it strange.

It could have been some military test, or aliens?

Azathoth, awakening ….

Most likely an airburst of a comet (or rocky meteor) breaking up in the atmosphere.

Consider it a mini-Tunguska or other such impact.

Sonic boom.

Havent heard one of those since they banned the military from flying past the sound barrier...back in the late 60s and early 70s.

BA BOOM! Then you hear the sound of the jet engines sometimes.

Imagine the noise of a dump truck being dropped from 100 feet in the air onto pavement.

Excellent comparison.

I mean, who hasn't ever heard that sound before

Sonic boom. I had one here a few yrs ago that sounded like someone hit the side of my house with a big baseball bat.

If it was indeed a sonic boom but it sounded as you describe, the object making it must have been at very high altitude.

5 days ago had some chasers upn`here mountains maybe 2000 ft altitude E-W at 9PM headed toward Saranac

Sounds like the Russians (or Chinese) were doing a bit of mapping here. Nothing to worry about.

All over the area up here in Placerville California there are mystery booms coming from the south..
Even a facebook page dedicated to it.

No one knows what causes them.

A sonic boom from a jet would not cover that amount of space. Maybe we were testing a super sonic missile like the Russians? Pittsburgh AFB has been closed for many years now, no more F-111s to blame.

Back in high school my BIL and his buddies made a big propane cannon that they would drag out of the garage after midnight and fire it.

Rattled windows for a mile around and made the local paper and could be heard in towns up and down the valley.

"Residents call 911 to report mystery booms".

Though rare, New England stills experiences tectonic activity. The Moodus noises” have been known phenomena for centuries.

[Rebelbase]

Didn’t the same kind of thing happen last year and eventually a perp blowing off homemade bombs was caught?

DARKS!!! What did you DO???

Somebody’s moonshine ain’t gonna be for sale this fall.

when we were kids- we used to hear what they called ‘sonic booms’ all the time- jets- had one fly right over us and had it happen- then some sissified complained, breaking the sound barrier became a huge no no- and now you very rarely hear it and when you do, it becomes a national scandal

Swamp gas. No swamps? Cow farts then. Definitely not aliens...
