Size: Approximately 27,807 acres – Location: Santa Teresa Mountains, Graham County, Arizona – Smoke: The Pinnacle fire is producing significant smoke. For current air quality click hereContainment: 15% – Cause: Under Investigation – Start Date: June 10, 2021 – Total Personnel: 428 

SANTA TERESA WILDERNESS – Friday was another day of high heat and low humidity with the fire finding new sources of fuel. The result was another day of active fire behavior and the generation of a significant smoke column. At about 2 p.m., a large column of smoke could be observed as the fire consumed new fuels within the wilderness, causing it to move west. 

Crews and fire managers worked thru the day and last night to prepare and plan for actions to mitigate the fire’s western movement once it travels to more manageable terrain outside the federally designated wilderness area. Fire managers will focus on this segment of the fire in the next few days. 

The eastern perimeter of the fire remained calm with little to no smoke. Fire in the Black Rock Ranch area was moderate. However, at Black Rock, structure protection sprinklers, pumps, and water blivits remain in place, prepared to be activated should the fire again move in that direction. On the southwest section, firefighters continued to patrol and reinforce fire lines near Klondyke as the fire cools from recent suppression activities.
