Table 2 Count of large (> 121 ha) lightning-caused USFS POO wildfires (excluding complexes) by maximum single-day fire spread rate (ha) and overall growth duration (weeks) from 2009 to 2020. The subset adopted for further analysis (i.e., fires with single-day growth > 2023 ha and > 14-day duration) is shaded in gray (fires n = 40, after excluding 2020-WYMRF-Middle Fork)). These 40 fires CB characteristics were determined, resulting in 8 fires that did not exit USFS lands, leaving 32 analog fires
