Investigators have determined that fireworks launched in a restricted area sparked a brush fire above Provo’s Slate Canyon on the Fourth of July.

The Provo Fire Marshal’s Office has not identified a suspect, but officials issued a public appeal seeking information related to the blaze, which came after the city had banned personal fireworks over the holiday weekend.

Officials requested that individuals with photos, video or information related to the fire, around the time of 10:40 p.m., to call 801-852-6321 or email fireprevention@provo.org.

“This incident reinforces why Provo Fire and Rescue supports proactive wildfire prevention measures,” Provo Fire and Rescue said on social media. “The temporary closure of the BYU Y Trailhead during periods of extreme fire danger helps reduce risk in an area with a single access point, steep terrain, and significant life-safety concerns. It also underscores the importance of preventive measures such as the fireworks ban and Stage 2 fire restrictions, which are designed to reduce the risk of human-caused wildfires before they start.”

The Provo fire came the day after kids lighting fireworks started a Davis County brush fire that forced several Kaysville residents to evacuate their homes late Friday.

Both blazes came during a period when personal fireworks were barred in much of Utah due to extreme wildfire risk.
