Stratiform-region CG lightning flashes often ground a negative charge region centered just below cloud base, the same charge region that allows crawler and spider lightning to be visible. This results in spectacular displays where most (if not all) lightning activity from an active portion of a flash can be seen, including the components involved in removing cloud charge to ground which are usually hidden deep inside the cloud.
The two cases shown here are from two separate events, both within stratiform regions of loosely-organized mesoscale convective systems.
NLDN-detected events:
Case 1: CG -63kA (!), IC -16kA, CG -8kA
Case 2: All -CGs; 28kA (left), 28, 21, 14, 12kA (right, order unknown). Missed event was probably the very weak 3rd stroke.

Lightning information provided by Vaisala's National Lightning Detection Network (NLDN) through weather.us/lightning. Note that I only use this information to roughly estimate stroke intensity and distance, the data may be prone to error on my end, and my work is not, and should not be considered to be, a formal evaluation of the NLDN's performance.
Thanks to Tom A. Warner and other lightning physicists and researchers who have helped me understand lightning processes explained in my videos. Tom has created a great resource for individuals interested in learning how lightning works.
