Beetle-killed and fire-killed snags from the Pole Creek Fire (2012), Oregon, USA, sampled for pyrogenic carbon analyses in June 2018. (A, B, and C) Charred bark on fire-killed snags with exposed unburned wood, demonstrating lighter charring. (D, E, and F) Charred bark and wood on beetle-killed snags that had evidence of mountain pine beetle activity (i.e., J-shaped galleries) and were considered to be dead before fire, demonstrating heavy charring. Photos were taken during sampling in June 2018. Photographer credit: L. Matosziuk and A. Talucci
