A large fire broke out at a house in Denver's Englewood on Thursday afternoon, with black smoke visible from around the city.
Denver Fire and Englewood PD responded to the scene on West Harvard Avenue, with locals sharing visuals of the fire on social media.
Despite the smoke being visible from up to 25 miles away, the fire was classified as a single-alarm blaze.
No injuries have been reported, but the cause of the fire is still under investigation.
The Denver Fire Department described the fire as 'stubborn,' with hoarder conditions making extinguishment difficult due to extreme heat and flames.
Crews are working aggressively to bring the fire under control, with two extra engines and one truck added to the initial response.
