4 Grizzly Bear Complex (2015) Wenaha-Tucannon Wilderness, Umatilla NF, NE Oregon 18 starts from lightning (Aug. 13) Dry cold front passage with strong winds increased fire size to 2,000 acres; 13 fires grew together (Aug. 16)

Historical fires (e.g., School 2005)? A nearby fire currently burning in similar terrain, fuels, and elevation (i.e., Eagle; WWF)?
