A fire on Mount Lemmon, possibly caused by a lightning strike Sunday evening, is still burning this morning.

The fire is burning near an area known as Prison Camp, just west of milepost 8 on Catalina Highway, said Heidi Schewel, a spokeswoman for the U.S. Forest Service. 

Two fire engines, three crews and several firefighters were battling the blaze.
