Capt. Chris Quinn of the Sacramento Metropolitan Fire District said the fire was reported about 2 p.m. The first crews arriving spotted what appeared to be two fires, one burning near the El Manto Drive access to the parkway, north of Coloma Road, and the other to the west, near the Rossmoor access.
Additional personnel and resources were requested, including a helicopter and dozers. Quinn said the fires quickly merged into one fire.
He said the fire was burning in an area of grass and oak trees with rolling hills and river rock tailings. The wind-driven fire spread quickly, but, fortunately, Quinn said, it was driven north toward the river and not toward the residential area to the south. It was contained in about two hours.
No homes were threatened and no one was injured.
Quinn said the bike trail south of the river was closed for a while because the fire was burning right up to the trail. It has since reopened.
The cause of the fire has not been determined, and Quinn said investigators are on scene. He said crews will be mopping up into the evening.
