A comparison of Visible images from GOES-15 (GOES-West), GOES-17 and GOES-16 (GOES-East)  on 14 July 2018 is shown above — in addition to thunderstorms over the high terrain of the Sierra Nevada, the development of a pyrocumulus cloud (with a small overshooting top) can be seen over the Ferguson Fire that had been burning for nearly a day near Yosemite National Park in central California.

Images from GOES-16/17 are at 5-minute intervals, while image intervals from the older GOES-15 satellite range from 5-30 minutes. The improved spatial resolution of the GOES-16/17 0.64 µm visible imagery (0.5 km at satellite sub-point, compared to 1.0 km for GOES-15) allowed finer details of the overshooting top to be seen — and the improved image-to-image navigation of the new GOES-16/17 satellites was also apparent (note the significant navigation errors in a few of the GOES-15 images).

A photo from the ground (below) showed a large pyrocumulus cloud towering over the top of the dense smoke.
