A small grass fire in Jackass Hill Park that began around 9:40 p.m. March 24 may have been caused by fireworks, said South Metro Fire Rescue spokesperson Eric Hurst.
"Neighbors only heard fireworks, they didn't see anyone shooting them off and there was no one in the area of the fire when our firefighters arrived," Hurst said.
Hurst said the fire was extinguished just after 10 p.m. with the last officer leaving the scene around 10:20 p.m. The fire posed no threat to residents or structures, Hurst said.
Firefighters found a single, unexploded bottle rocket near the fire, Hurst said, but there was no other evidence as to what started it.
"The official cause is undetermined but possibly related to fireworks," Hurst said.
Littleton resident David Sprunt, who lives on Sunset Drive just 50 yards from where the fire burned, said neighbors used a fire extinguisher and stamped on flames to put out the fire, which burned several hundred square feet.
"We often hear illegal fireworks fired on the hill during the summer, especially around the Fourth of July, it’s a miracle we haven’t seen a fire before now," Sprunt said.
