Air Ops reports fire on south Martin Ridge (NE part of fire) is actively backing into Little Sand Creek with group tree torching. The south part of the fire continues to back into the Piedra River with switching winds. Two heavy helicopters are working the fire’s edge to slow its progress toward the river. The NW part of the fire continues to burn but less actively than other areas of the fire. There are reports of ash fall last night in the Vallecito Reservoir area; it is believed this is from the Weber Fire near Mancos.
