The investigation continues into what caused the fire Sunday night that destroyed a multi-million dollar home northwest of Jackson. Fire Marshal Kathy Clay says little remains of the structure despite the efforts of approximately 40 firefighters from multiple Jackson Hole Fire Stations and Grand Teton National Park. Clay says firefighters efforts were hampered by bitter cold temperatures which dropped to at least -20°. She explains that when temperatures are that low, there are two overriding problems: first is how the firefighters can work under those extreme conditions. Clay says, “Essentially when you are working with water you become encrusted with ice, you can’t move your gloves, you’re cold — your feet are cold, your fingers are cold – and your visor is frosted up.” Second, she says the cold presents risk to the equipment. When water freezes, it expands and easily can damage the equipment in the process of putting out a fire in twenty-below temperatures. Clay says firefighters were taken off the fire 12 hours after the initial call, but returned six hours later to knock down some remaining hot spots in the ruins. They finally cleared the scene about 5:00 pm Monday. Clay says the fire was initially reported as a chimney fire, but first responders soon reported smoke was coming from areas other than the vicinity of the chimney. While firefighters were unable to save the house, Clay says they salvaged many valuable possessions before the building was consumed. Most importantly, Clay says the occupant and her dog escaped uninjured. Clay says she anticipates making a determination on the fire’s origin by Tuesday afternoon.
