The GOES-14 satellite was placed into Super Rapid Scan Operations for GOES-R (SRSO-R) mode on 13 August 2013, providing imagery at 1-minute intervals. The development of a well-defined pyrocumulonimbus (pyroCb) cloud produced by a large fire burning to the east of Boise in southern Idaho can be seen in a comparison of GOES-14 0.63 µm visible channel and 3.9 µm shortwave IR channel images (above; click image to play animation). The hottest pixels in the shortwave IR images are enhanced with a red color.

Judging from 250-meter resolution MODIS true-color and false-color images from the SSEC MODIS Today site (below), the pyroCb was spawned by fires burning along the eastern/northeastern periphery of the large burn scar (which appears as the  red to brown feature on the false-color image) of the merged Pony and Elk Fire Complexes.
