NASA captured images of pyrocumulus cloud formation on August 2 with images from two earth-orbiting satellites. "The pair of natural-color images documents the evolution and rapid expansion of the fires," NASA said. "Many areas of active burning expanded significantly between the satellite overpasses, as smoke plumes blossomed into towering pyrocumulus clouds. The change was most dramatic over the Beaver Complex fire along the border of California and Oregon."
