Tri-Township firefighter Matt Sirtola hoses down smoldering hay bales while David Hammar operates a skidster at his farm on North Rock 38th Road in Rock in northwest Delta County on Sunday. Spontaneous combustion is said to be the cause of the fire which destroyed several bales of hay. Firefighters were dispatched to the scene around 4:30 p.m. and fought to control the fire for nearly five hours.
