A small fire south of Payson along Highway 87 near Oxbow Hills was contained by fire crews on Saturday.
The Oxbow Fire, which began around noon, reached one acre before crews had it under control, said Fire Prevention Officer Gary Roberts.
Four engines and one helicopter responded to the blaze.
The Payson Fire Department assisted in the efforts.
Roberts said the cause of the fire is still undetermined.
"We've had quite extreme conditions for most of June," he said. "With conditions like this, I can't even guess as to why we haven't had more fires than we have. I'm grateful we haven't."
Roberts said it appears the lower number of fire ignitions so far this fire season can be attributed to people exercising more caution.
Fire restrictions continue to be in effect over the Fourth of July holiday.
Campfires, charcoal-burning fires and smoking in the forest are among the restrictions.
