The Lookout Fire ignited by lightning on August 5th, 2023, on the H. J. Andrews Experimental Forest (HJA) within the Willamette National Forest in Oregon. Fire growth to the northwest in the Lookout and McRae Creek drainages provided opportunities for the Fire Behavior Assessment Team (FBAT) to install plots ahead of the fire in forest with old-growth characteristics, including large overstory trees and downed logs, many of which had rotted into duff. We installed plots primarily in stands dominated by large Douglas firs with a significant representation of smaller western hemlock, western redcedar, and yew. Past snag felling had occurred in and around some plots that were near roads or clearcut blocks. Surface fire was the dominant spread mode through plots and consumption of duff and downed logs was substantial. Seven of 12 plots we installed burned between 14 and 19 September, 10-15 days after a wetting rain.
