The wildfire burning at a low elevation on Mount Lemmon was expected to be contained by day's end Saturday, Forest Service officials reported. It was completely put out by Sunday morning.

The Prison Fire, burning near Molino Basin, had consumed 270 acres of grass, brush and some scrub oak, a slightly lower acreage estimate than had been made earlier in the week, according to the federal Incident Information System website.

No structures were being threatened by the fire, which was lightning-caused and started Sunday evening. The fire was reported to be 50 percent contained on Friday, meaning a stable fire line was in place halfway around the burning area.

Coronado National Forest officials said that as a reminder, visitors to Arizona wild lands are restricted in uses of fire. All campfires, welding, target shooting and smoking are banned. Fireworks also are banned on Forest Service land.

Use of pressurized liquid or gas stoves, lanterns and heaters possessing shut off devices are allowed but must be used in areas clear of grass and other fine fuels, officials said in a press release.
