The Wragg Fire started just over the ridge to the west of Cold Canyon, rushing quickly over the hill and down into the canyon.  Once there, it remained in the canyon, generating winds that caused it to cycle within the canyon, according to Jeffrey Clary, Stebbins Cold Canyon Reserve Manager.  This greatly increased the intensity of burning in the canyon.  The differences in fire intensity across the landscape burned will lead to interesting opportunities to compare rates and types of regrowth in the coming years.
