A 300-acre wildland fire in Lake County ran its course Wednesday with the help of rain.

A state forestry spokesman said the fire on Mt. Konocti was fully contained by 10 a.m. Wednesday, thanks in part to falling rain.

Initial reports indicated the fire started as a controled burn in the Kelseyville area, which jumped its borders late Tuesday morning.

Cal Fire Capt. Tiffany Mercado Wednesday said the cause of the 296-acre fire remained under investigation.

Fire crews worked in an area near Highway 29 and Red Hills Road near Mount Konocti. The fire didn't threaten any structures.
