Utah officials were forced to blow up a house in a controlled explosion after the homeowner found old dynamite. 

The Unified Fire Authority blew up a house in Holladay at 4 am on April 24 after the female owner found large amounts of old dynamite stashed in her deceased husband's belongings. 

According to officials, the explosive material had been passed down from generation to generation before the elderly woman found it.

'She knew it was dangerous, she didn't know the extent but knew she needed help taking care of it,' said Unified Fire Authority Assistant Chief Riley Pilgrim.

The Assistant Chief believes that the dynamite was about 40 to 60 years old. Firefighters were able to find 25 sticks outside and eight in the basement near various chemicals.

'Because of the age and the crystallization and deterioration of the product it just became way too dangerous to handle even taking one stick out could've created a significant threat to our personnel,' he said. 

As a result, approximately 450 homes were evacuated in Holladay before the blast.
