The lightning-caused fire began to spread in the first week of June 2020.
Here's an interactive timeline that documents some notable moments:
Residents in the area of the fire were advised to evacuate days after it started, including people who lived in Pima Canyon, Willow Canyon, on Mount Lemmon, and east of the Catalinas.
As the fire continued to grow, it was declared a major disaster, and FEMA funds were eventually sent to the state to cover firefighting costs.
As the number of acres burned kept increasing, residents affected in 2003's Aspen Fire reflected on the similarities.
On June 22, the Bighorn Fire had the largest firefighting crew in the US.
KGUN 9 spoke to a storm chaser who photographed the bolt that sparked the fire.
Federal fire officials announced that the Bighorn Fire was 100 percent contained on July 23, 2020.
