The Tank Hollow Fire was first reported on August 11, 2017 at 9:45 AM at Sheep Creek in the Uinta-Wasatch-Cache National Forest, approximately 19 miles east of Spanish Fork, Utah.

The fire was started by a lightning strike and was fueled by timber, grass, and brush, including juniper, sage, mixed conifer, and Douglas fir.

The fire creeped back into Sheep Creek and moved south east towards US Route 40, threatening homes.

Heavy winds forced fire crews to leave Corral Canyon due to safety reasons.

[5] On August 30, crews continued to help keep the fire from Tie Fork Rd., using the road itself, natural barriers and hand digging.

Cooler and wet weather helped dampen the fire, creating smoldering in many areas.

A Temporary Flight Restriction was put in place earlier during the fire and during late August and early September, there were six airspace intrusions due to uncleared pilots flying into the area.
