Strong winds driven by local topography pushed the fire to the northeast.  The fire grew to 15,075 acres.  Most of the residences west of Highway 89 were evacuated.

The Schultz Fire was started by an abandon campfire.

Fire fighting equipment included  8 air tankers, 7 helicopters, 62 fire engines, and 13 water tenders.  Firefighting efforts alone cost around $10 million dollars.  No homes or buildings were damaged by fire.  However,  flooding and debris flows that resulted from the fire damaged landscape caused damage to close to 100 properties and homes once the rainy season started in July and lasted through August.
