The Jack Knife Fire was reported on June 22, 08:11 a.m. after a storm brought patchy rain and lightning through Central Oregon.

The fire was burning in heavy sage brush and grass, with scattered juniper. Grass in the area is unseasonably dry facilitating rapid fire spread. The fire area is located in remote and rugged terrain within the Lower John Day Wilderness Study Area.
