Amador County - A fire that threatened to engulf a house in flames was quickly extiguished thanks to the quick response of firefighters Tuesday evening. The fire began at the rear of a home on Debbie Lane in Pine Grove. The fire could have threatened several surrounding structures, but was brought under control by fire crews within fifteen minutes of the blaze’s inception, at 6:45 Tuesday evening. When Fire Battalion 10 first arrived on scene, the rear of an adjacent building to the home was heavily involved in fire. Negotiating a narrow driveway on a steep hill, fire fighters were able to set up hose lines and quickly knock back the flames before they spread any further to the building and the adjacent home. Fire personnel are still investigating the cause of the blaze. Bill Lavallie contributed.
