Some people thought that it was thunder due to the amount of rain that fell in the area over the weekend. Others said it sounded like a vehicle crashing into a building.

The sound was so loud that it was heard in West Yellowstone, and reportedly shook windows in the homes of some Bozeman residents.

An anonymous user on the Secret Bozeman Facebook page asked;

Did anyone hear that giant boom at 5:47? Was that an earthquake? Sonic boom? Sounded like someone ran into our house!

Many people that heard the loud boom thought that it was most likely thunder, but some residents aren't convinced. Residents offered a variety of explanations. Some were certain it was a sonic boom caused by the sound barrier being broken, while others said it sounded like a large amount of tannerite exploding.

Could it have been the sound of a military fighter jet, such as an F35?

The loud boom was heard by residents in Bozeman, Belgrade, Four Corners, West Yellowstone, and Livingston. Despite all of the various speculation, the cause of the sound is still unknown.
