Burning conditions in the Yosemite Forest Dynamics Plot during the 2013 Rim Fire backfire. The backfire was ignited at the Crane Flat Lookout (A) during the afternoon of 1 September 2013, approximately 1 km from the plot. The energy release component (B), maximum temperature (C), maximum sustained wind speed (D), and relative humidity (E) during the period of fire activity were higher than typical for management ignitions. The shaded area (B through E) delineates the period of active burning. The fire backed downslope to the plot (F) and burned within the plot at moderate (G) to lower severities during the night of 1 September 2013 (H) and the morning of 2 September 2013 (I). Fire weather data from Ewell et al. (2015). Photo credits: Andrew “Boots” Davenport (A), Gus Smith (F, H, and I). Photo G is a video still from an FBAT camera, eight minutes after the video was triggered by thermocouple.
